Explanation:
It is known that for each one tablespoon of dry tea we need 2 cups of water if we want to make two cups of tea.
As 1 cup has 16 tablespoons.
Hence, number of tablespoons present in two cups of water will be as follows.
1 cup contains 16 tablespoons
2 cups will contain = 2 × 16
= 32 tablespoons
Therefore, the stoichiometry is 1 : 32.
Thus, we can conclude that the molar ratios from balanced equations is 1 :32.
Answer: The volume of the gas is 1.98 L.
Explanation:
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus the volume of the gas is 1.98 L
part 1 sodium and rubidium have the same properties with potassium. this is because sodium, potassium, and rubidium are in the same column that is they are all in group one of periodic table. all are alkali metals hence have the same properties.
part two
magnesium have 12 neutrons, 12 protons and 12 electrons
from periodic table the magnesium is atomic number 12 and has a mass number of 24.305
The atomic number is equal to number of protons that is 12
protons value is the same as electron value hence the number of electron are also 12
mass number=protons +neutrons hence
Neutron=mass number-number of protons that is 24.035-12=12 which is equal to 12 neutrons
<h2>Answer:</h2>
The cumulative change in these characteristics is known as genetic diversity.
<h3>Explanation:</h3>
- Genetic diversity in the population means the increase in the number of genetic/allelic combinations in the population.
- For example, a population of contains 5 genes for the fur color. With the passage of time, these 5 genes will produce 25 genetic combinations of this phenotype. This will be known as the genetic recombination.
- Genetic diversity is due to mutations, random breeding, and random gene flow.
- Genetic diversity is the cause of some animals of the species to adapt to changing environment.
Explanation:
- a single thing, person, or group forming part of a whole There are 36 units in my apartment building.
- the least whole number : one.
- a fixed quantity (as of length, time, or value) used as a standard of measurement An inch is a unit of length.
