The density of ice is 0.9167 g/cm<span>3</span>
Answer:

Explanation:
1. Take in account the sulfuric acid at STP:

2. Density is expressed as the ratio between the mass and the volume of a substance so:

Solving for m:

3. Replace values:


Answer: The rate constant is
Explanation ;
Expression for rate law for first order kinetics is given by:

where,
k = rate constant = ?
t = age of sample = 4.26 min
a = initial amount of the reactant = 2.56 mg
a - x = amount left after decay process = 2.50 mg
Now put all the given values in above equation to calculate the rate constant ,we get



Thus rate constant is [tex]0.334s^{-1}
Answer:
mass and speed
Explanation:
the motion of an object depends on how fast it's travelling and also how much mass it has
