Answer: The coefficient is 3.645
The exponent is 1
There are 4 significant digits
The rightmost significant figure is 5
Explanation:
Scientific notation is defined as the representation of expressing the numbers that are too big or too small and are represented in the decimal form with one digit before the decimal point times 10 raise to the power.
For example : 5000 is written as
According to avogadro's law, 1 mole of every gas contains avogadro's number of particles, occupy 22.4 L at STP and weighs equal to its molecular mass.
131.29 g of Xe occupy = 22.4 L at STP.
Thus 213.62 g of occupy = at STP.
Scientific notation =
The coefficient is 3.645
The exponent is 1
There are 4 significant digits
The rightmost significant figure is 5
Answer:
The majority of the molecules move from higher to lower concentration, although there will be some that move from low to high. The overall (or net) movement is thus from high to low concentration.

Answer:
a. The skull could support as much as 3 tons of weight.
Explanation:
The true statement about brain is
a. The skull could support as much as 3 tons of weight.
The cranium(skull) bones are slot like a jigsaw puzzle together. All but one of these bones is fixed in place in adults. It makes the skull very solid. Babies have holes between the cranial (skull) bones so that as they are born, their heads may withstand being crushed.
rest all statements are wrong.
The limiting reactant will be HCl.
<h3>Limiting reactants</h3>
They limit the amount of products produced in reactions.
From the equation, the mole ratio of Mg to HCl is 1:1.
Mole of 4.00 g mg = 4/24.3 = 0.1646 moles
Mole of 3.2 g HCl = 3.2/36.458 = 0.0878 moles
Thus, Mg is in excess while HCl is limiting in availability.
