Answer:
c
Explanation:
because when you hold a solid in your hand does it move does it shift no it stays the same so it doesn't take the form of the container it's in cuz that's a liquid.
The rate of the backward reaction increases
Explanation:
It is evident that if the reaction is left to proceed spontaneously, the forward reaction is favored because it results in a decrease in pressure in the system (The total reactants have 5 moles and the products have 3 in total).
Increasing H₂O concentration is then reaction, therefore, stymies the forward reaction and favors the reserves reaction. This is because the reverse reaction will lead to reduced pressure.
Answer : The mass of 7.0 m chain is, 15.12 kg
Explanation :
As we are given that,
The weight of the chain per unit length = 2.16 kg/m
Now we have to determine the mass of chain for 7.0 m length.
As, the mass of 1 m length of chain = 2.16 kg
So, the mass of 7.0 m length of chain = 
= 15.12 kg
Therefore, the mass of 7.0 m chain is, 15.12 kg
Answer:
The answer is letter b, mixture.
Explanation:
Let's define what a mixture is at first.
Mixture- In Chemistry, mixture is a material made up of two or more different substances that are physically combined. The identities of the substances are retained. There are two types of mixture: <em>homogenous and heterogenous.</em>
<u>Homogenous mixture</u> examples: saline solution and air.
<u>Heterogenous mixture</u> examples: sand and oil and water.
The student's record shows the color of the substance as yellow, shiny powder. It could mean that the substance is a mixture of different kinds of powders. This is already a hint, since powder is a form of mixture. The record also shows that the substance is attracted to magnet. Part of the powder mixture contains something that is attracted to magnet. It could be an iron powder, which is the shiny one. The substance can then be classified as letter b, mixture.
