Answer:

A. your reaction makes more products.

Explanation:

This is a fun question dealing with idea of Le Chatelier's principle.

In an exothermic reaction, you produce heat. This means that heat will act as a product (or be on the product side).

Suppose there's an imaginary equation:

A + B -----> C (Now if I lower the amount of B, the equilibrium will shift to left to make up the lost B, or to bring the system back to equilibrium)

Apply the same concept as above below:

A + B -------> C + Heat (as I mentioned, since this is exothermic reaction heat is written as product, so if you lower the temperature, which means basically lower the heat, the reaction will shift towards right to make up the lost heat, in this process you will make extra C which is products. Thus, your reaction makes more products.

What is an atom that has the same number of protons as other atoms of the same element, but has a different number of neutrons?
PSYCHO15rus [73]

Answer:

isotopes

Atoms with the same number of protons but different numbers of neutrons are called isotopes. Because the number of neutrons can vary for a given element, the mass numbers of different atoms of an element may also vary. For example, some helium atoms have three neutrons instead of two (these are called isotopes and are discussed in detail later on)

The amount of 217 mg of an isotope is given by A(t) = 217 € -0.0171, where t is time in years since the initial amount of 217 mg
Maru [420]

The amount left after 20 years = 154.15 mg

<h3>Further explanation </h3>

The atomic nucleus can experience decay into 2 particles or more due to the instability of its atomic nucleus.  

Usually radioactive elements have an unstable atomic nucleus.  

The main particles are emitted by radioactive elements so that they generally decay are alpha (α), beta (β) and gamma (γ) particles  

The decay formula for isotope :

\tt \large{\boxed{\bold{A(t)=217e^{-0.0171t}}}

Then for t=20 years, the amount left :

\tt A(t)=217e^{-0.0171\times 20}\\\\A(t)=154.15~mg

The solubility of copper(i) chloride is 3.91 mg per 100.0 ml of solution. calculate ksp for cucl (cucl=99.00 g mol-1).
garri49 [273]
Convert  Mg  to  grams
1g =1000mg  what  about  3.91  Mg
=  3.91mg  x  1g/1000mg=  3.91  x10^-3 g
moles= mass/molar mass
that  is  3.91  x10^-3g  /99 g/mol=3.95 x10^-5moles
concentration=   moles  /  vol   in  liters

that  is  3.95  x10^-5/100  x1000=  3.94  x10^-4M

equation for  dissociation  of  CUCl=   CUCl---->  CU^+   +Cl^-

Ksp=(CU+)(CI-)
that  is  (3.95  x10^-4)(3.95  x10^-4)
Ksp=  1.56  x10^-7

What is the volume of 88 grams of CO2 gas at STP?
I am Lyosha [343]
! mole of CO2 at STP has a volume of 22.4 liters
88 grams = 2 moles 

so the required volume = 2*22.4 = 44.8 liters
