Answer:
1) eathquake
earthquake is the natural calamities where there is the vertical and horizontal shaking of the
earth crust. it is cause due to overlappibg of the different plates that are present in the earth surface. when this plates intersect or expand the earth occurs
consequences are it causes loss of life and human property , degards the environment , it leads to flood, landslides etc The damage caused by earthquakes is from ground shaking, ground rupture, landslides, tsunamis, and liquefaction.
Next - volcanic eruption
its is the out flow of the larva from the inner of the earth to other surface. it is cayse due to high pressure exerted on the surface of the earth that leads to explode the inner larva.
its consequences are it degards the environment and loss of the beauty of the nature , there is loss of human life , widlife , etc. volcanic eruption include infectious disease, respiratory illness, burns, injuries from falls, and vehicle accidents related to the slippery, hazy conditions caused by ash. When warnings are heeded, the chances of adverse health effects from a volcanic eruption are very low.
what causes magic milk
Answer:
don't know exactly but surely have helped u
Answer:
The fat and proteins are super sensitive to changes in the milk and so when the dishwashing liquid is added a chemical reaction occurs. The soap and fat work hard to join together, which causes the movement. When food colouring is added we are able to witness this chemical reaction occurring.
Explanation:
True or false? During a change of state the temperature of the substance does not change.
Answer:
false
Explanation:
the temperature of a substance can not remain constant as the substance changes from solid to liquid then finllay from liquid to gas. This is so because as a solid is heated it changes state and once it rechanges it boiling point it changes to gas or vapour.

How does a positive ion form?
Answer: Metal atoms lose electrons from their outer shell when they form ions: the ions formed are positive, because they have more protons than electrons.
Explain the solute and the solvent in a solution
Answer:
a solute is a substance that is dissolved in the solvent (liquid)
a solvent is a substance that dissolves a solute (solid)
a solution is the mixture of both the solute and solvent forming uniform mixture
The same amount of force is applied to bowling balls one of the balls Waze 8 pounds and the other weighs 13 pounds which bowl will have a greater acceleration
Answer:
The bowling ball with mass 8 pounds has greater acceleration.
Explanation:
The acceleration on the objects is equal to the quotient of the force applied on it and its mass. From Newton's second law of motion, we have;
F = ma
where F is the force on the object, m is its mass and a is its acceleration.
⇒ a = [tex]\frac{F}{m}[/tex]
Let us assume that a force of 50 N was applied on the two bowling balls.
Thus;
mass of the first bowling ball = 8 pounds = 3.62874 kg
So that,
50 = 3.62874 x a
a = [tex]\frac{50}{3.62874}[/tex]
= 13.779
The acceleration of the first ball is 13.78 m/[tex]s^{2}[/tex].
For the second ball of mass = 13 pounds = 5.8967 kg
So that,
50 = 5.8967 x a
a = [tex]\frac{50}{5.8967}[/tex]
= 8.4793
The acceleration of the second ball is 8.48 m/[tex]s^{2}[/tex].
Therefore, the bowling ball with mass 8 pounds has greater acceleration.

Answer:
Assuming the element Magnesium atom is neutral
Proton # = 12
Neutron # = 12
Electron # = 12
Explanation:
In a neutral atom the number of protons and electrons is always equal
The atomic number tells the number of protons (12) in this case
The Atomic Mass describes the mass of the protons + mass of neutrons, so if you take 12 (number of protons) away you are left with 12 and some change(number of neutrons)

why same amount of food in large bowl gets cooler than that of food in smaller bowl?
Reasoning 1: On a general base, you have more surface area exposed so more air molecules (if you're not having a meal in outer space) come in contact with the food, absorbing heat energy, cooling it down.
Ok, so this is only one reason if your food is dehydrated 'to the core'.
Reasoning 1 + 2: Most foodstuff contain moisture. This moisture evaporates on absorbing heat energy from surroundings. This causes a temperature decrease of the food surface.
Looking upon the basic factors that alter evaporation rate, more surface area exposure causes a faster evaporation rate, hence, faster cooling rate.

Calculate the amounts of each substance in the reaction below if an initial amount of 0.400 moles are brought together with an initial amount of 2.29 moles of Cl2 in a 1.00 L vessel
Complete Question
Calculate the equilibrium amounts of each substance in the reaction below if an initial amount of 0.400 moles of CO are brought together with an initial amount of 2.20 moles of Cl2 in a 1.00 L vessel and then equilibrium is established at 900 K. Kc at this temperature = 0.800. COCl2(g) CO(g) + Cl2(g)
Answer:
The amount of each substance at equilibrium is
[tex][COCl_2 ] = 0.282 \ M[/tex]
[tex][CO] = 0.12 \ M[/tex]
[tex][Cl_2] = 2.008 \ M[/tex]
Explanation:
From the question we are told that
The initial amount of CO is [tex]n_1 = 0.400[/tex]
The initial amount of [tex]Cl_2[/tex] is [tex]n_2 = 2.20 \ moles[/tex]
The volume of the vessel is [tex]V = 1.0 \ L[/tex]
The temperature is [tex]T = 900 \ K[/tex]
The equilibrium constant at the given temperature is [tex]K_c = 0.800[/tex]
The reaction is
[tex]COCl_2 \underset{}{\stackrel{}{\rightleftharpoons}} CO + Cl_2[/tex]
Now Generating an I C E table
[tex]COCl_2 \ \ \ \ \underset{}{\stackrel{}{\rightleftharpoons}} \ \ \ \ \ \ \ \ \ CO \ \ \ \ \ \ \ \ \ \ + \ \ \ \ Cl_2[/tex]
Initial [I] 0 0.400 2.20
Change [C ] + x -x - x
Equilibrium [E ] x 0.400- x 2.20 - x
Here x is the amount in terms of concentration by which [tex]COCl_2[/tex] and [tex]CO[/tex] and [tex]Cl_2[/tex] decreased during the reaction
Generally the equilibrium constant is mathematically represented as
[tex]K_c = \frac{[CO] [Cl_2]}{[COCl_2]}[/tex]
=> [tex]0.800 = \frac{[0.400 - x] [2.20 - x ]}{[x]}[/tex]
=> [tex]0.800 x = [0.400 - x ] * [ 2.20 - x ][/tex]
=> [tex]x = 0.282 \ M[/tex]
Generally at equilibrium the amount of [tex]COCl_2[/tex] present is
[tex][COCl_2 ] = 0.282 \ M[/tex]
Generally the equilibrium the amount of [tex]CO[/tex] present is
[tex][CO] = 0.400 - 0.282[/tex]
=> [tex][CO] = 0.12 \ M[/tex]
Generally the equilibrium the amount of [tex]Cl_2[/tex] present is
[tex][Cl_2 ] = 2.29 - 0.282[/tex]
=> [tex][Cl_2] = 2.008 \ M[/tex]

Ammeter is connected in series and voltmeter is connected in parallel to the electric load in an electric circuit .
Answer:
An ammeter is a device that is used to measures the amount of current flowing in a circuit and a voltmeter measure electric potential difference in an electric circuit between two points.
An Ammeter is connected in series because of its low resistance capacity and it will be connected in parallel it can get damaged due to high current. A voltmeter is connected in parallel in an electric circuit because the potential difference remains the same when connected in parallel.
Under careful and controlled supervision, Ashley is slowly adding 1 mL of a strong acid at a time to 30 mL of a strong base to measure the effect it had on the pH. What is the testing (independent) and outcome (dependent) variable of this experiment? What would a good control be?
Answer:
The independent variable is the volume of the strong acid added to the strong base
The dependent variable is the effect of the combination of the acid and base on the pH
Explanation:
The given parameters are;
The rate at which Ashley is adding the strong acid to the strong base = 1 mL per each time
The volume of the strong base to which Ashley is adding the acid = 30 mL
Therefore;
The testing, or independent variable of the experiment = The number of 1 mL volume of the strong acid Ashley adds to the strong base
The outcome, or dependent variable of the experiment = The measured (change) effect on the pH.
