Answer:
Humdity would decrease hence temprature would do the same, hence tundra are called deserts at times.
Explanation:
Half-life is the time required for decay of 50% of radio-active nuclei.
Thus, when radio-active material crosses 1st half-life, 100/2 = 50% radio-active material is left and remaining 50% is elapsed.
When, when radio-active material crosses 2nd half-life, 50/2 = 25% radio-active material is left and remaining 75% is elapsed.
When radio-active material crosses 3rd half-life, 25/2 = 12.5% radio-active material is left and remaining 87.5% is elapsed.
Thus, 2 <span>half-lives must elapse until 84 % of a radioactive sample of atoms has decayed.</span>
Both molecules are long chain based polymers of carbohydrates. This can easily be told based on the fact that the 3 main elements that make up a sugar are present C , H and O.
This would be C11H12O11 in terms of simple empirical formula.
Answer:
7.2 gm or 0.0072 Kg
