Answer:
False
Explanation:
Heres what its made of:
The core is made of hot, dense plasma (ions and electrons), at a pressure estimated at 265 billion bar (3.84 trillion psi or 26.5 petapascals (PPa)) at the center. Due to fusion, the composition of the solar plasma drops from 68–70% hydrogen by mass at the outer core, to 34% hydrogen at the core/Sun center.
The molarity = 0.454 M
<h3>Further solution</h3>
Given
Volume = 3 L of solution
mass = 140 g of NaBr
Required
The molarity
Solution
Molarity is a way to express the concentration of the solution
Molarity shows the number of moles of solute in every 1 liter of solute or mmol in each ml of solution
mol of NaBr :
= mass : MW
= 140 g : 102,894 g/mol
= 1.361
Molarity :
= 1.361 mol : 3 L
= 0.454 M
Answer:
5
Explanation:
the Carbon's atomic number is 6, but when its charge is 1+ it means that it lost an electron .. so 6-1=5
Its c ok im sorry if i got the last answer wrong
