Ferns reproduce with spores which existed the longest in Earth history.

Gymnosperms reproduce with cones and has needle-like, waxy leaves.

Angiosperms reproduce with flowers and newest type of plant in Earth history.

<h3>How ferns, gymnosperm and angiosperm reproduce?</h3>

Ferns reproduce with spores that existed the longest in Earth, gymnosperms reproduce through the formation of cones having needle-like, waxy leaves whereas angiosperms reproduce with flowers which turns into seed. The newest type of plant in Earth history is also belongs to this group.

You have 357 ml of chlorine trifluoride gas at 699 mmHg and 45 celsius what is the mass of the sample
Maurinko [17]
To find the weight of the gas you need to find the number of moles of using ideal gas formula. Remember to change the temperature unit to Kelvin and the pressure to kpa or atm

PV=nRT
n= PV/RT
n= 699 mmHg* 0.1333kpa * 0.357 L/   8.314 kpa*L  / mol*K  * (45 +273.15)K
n=<span>0.012 moles
</span>
weight= n * molecular weight
weght= 0.012 *92.448 g/mol= 1.109 grams

Chemical substances that dissolve in water or react with water to release ions are known as
disa [49]
The answer is electrolytes. Strong electrolytes like strong acids, strong bases and salts dissociate completely into ions when dissolved and no neutral molecules are present in their solution. Weak electrolytes like weak acids and weak bases do not completely ionize in water and some neutral molecules are present in their solution, while nonelectrolytes do not dissociate into ions when in solution at all.

What is the molarity of a solution made from 325.4 g of AlCl3 (MM 133.34 g/mol) to make 500.0 mL?
NISA [10]

Answer : The molarity of a solution is, 4.88 M

Explanation : Given,

Mass of AlCl_3 = 325.4 g

Volume of solution = 500.0 mL

Molar mass of AlCl_3 = 133.34 g/mole

Molarity : It is defined as the number of moles of solute present in one liter of volume of solution.

Formula used :

\text{Molarity}=\frac{\text{Mass of }AlCl_3\times 1000}{\text{Molar mass of }AlCl_3\times \text{Volume of solution (in mL)}}

Now put all the given values in this formula, we get:

\text{Molarity}=\frac{325.4g\times 1000}{133.34g/mole\times 500.0mL}=4.88mole/L=4.88M

Therefore, the molarity of a solution is, 4.88 M
