Bond [772]

Answer:

increasing the number of molecules that have sufficient kinetic energy to react.

Explanation:

An increase in temperature affects the reaction rate by increasing the number of molecules that have sufficient kinetic energy to react.

or we say; temperature increase, leads to an increase in the amount of collisions between molecules.

Calculate the mass (in grams) of 8.56 moles of sulfur.
oksano4ka [1.4K]

Answer:

275g

Explanation:

Depending on the molar mass you are given, you can use that to solve this.

(I'm going based on my science class' molar mass of sulphur being 32.07g/mol)

Starting off, the formula for finding moles is

n=m/M (moles = mass / molar mass)

We can manipulate this equation to solve for mass.

m=Mn

now fill in what we now.

m = 32.07*8.56

mass = 274.5192

Now round for significant digits (if you are needed to do)

mass = 275g

CORO<br> Name three ways that scientists can ensure their results<br> are reliable
Leya [2.2K]

Answer:

Reliability. When a scientist repeats an experiment with a different group of people or a different batch of the same chemicals and gets very similar results then those results are said to be reliable. Reliability is measured by a percentage – if you get exactly the same results every time then they are 100% reliable.

Explanation:

Sorry, I only got one way.
