Anna [14]
First we have to understand what a half life is. A half life is a measure of time when the amount of a certain object is 50% of the original amount. Hence the answer for this is letter A. The initial amount is 100. fifty percent of 100 is 50 and that happens after 15 hours. Hence, 15 hours is the half life period.

(GIVING BRAINLYIST) Which environment has low temperatures and low humidity?
Greeley [361]

Answer:

The answer would be tundra.

A rain forest has a lot of humidity because it rains a lot otherwise it wouldn't be called a rain forest.

Grassland has a somewhat high temperature and average humidity enough to keep it green and grassy hence grasslands.

A wetland has a lot of water but low temperatures. Still, humidity is water so wetlands aren't it.

Explanation:

If a 0.4681 g Mg strip reacts with 0.650 M HCl in a 139.3 mL flask at 25oC, what is the minimum volume (mL) of HCl needed to com
Marizza181 [45]
The reaction between the magnesium, Mg, and the hydrochloric acid, HCl is given in the equation below,

    Mg + 2HCl --> H2 + MgCl2

The number of moles of HCl that is needed for the reaction is calculated below.
    n = (0.4681 g Mg)(1 mol Mg/24.305 g Mg)(2 mol HCl/1 mol Mg)
    n = 0.0385 mols HCl

From the given concentration, we calculate for the required volume. 
    V = 0.0385 mols HCl/(0.650 mols/L)
     V = 0.05926 L or 59.26 mL

<em>Answer: 59.26 mL of HCl</em>
