Answer: 0.4375 mols of solute
Explanation:
The problem is asking for the amount of solute. We are given the value of molarity. The molarity is 0.25M. We know that molarity is 
. Since we are given the liters of solution is 1.75, we can use those values to solve for mols of solute.
[multiply both sides by 1.75 L]
There are 0.4375 mols of solute.
Answer:
Protium
Explanation:
Isotopes -
For some elements , there are various forms possible , which have different number of neutron and same number of protons , are referred to as the isotopes .
The three isotopes possible for the element hydrogen are -
Protium , Deuterium and Tritium .
Where ,
- Protium has one electron , one proton and zero neutron.
- Deuterium has one electron , one proton and one neutron.
- Tritium has one electron , one proton and two neutron.
The most abundant isotope observed is Protium , with 99.98% abundance.
<span>At higher altitudes (and thus lower atmospheric pressures), water boils at a lower temperature. This is because the lack of vapor pressure at that altitude doesn't constrain the speed of the molecules with barometric pressure. Therefore, the water begins boiling at a lower temperature. This is often a disadvantage because even if the water is boiling, it won't be hot enough for meals (which is why heat and temperature are distinct). That's why we have pressure cookers, which manage to keep a stable boiling point.

Answer:
Because sodium is on the left side of the PT and phosporus is on the right side. And atomis radius decreases from left to right.
