Answer:
The number 10,847,100 in Scientific Notation is 
Explanation:
Scientific notation is an easy form to write long numbers and it is commonly used in the scientific field. To write a long number in a shorter way it is necessary to 'move' the decimal point to the left the number of positions that are necessary until you get a unit. Then you write the number and multiplied it by 10 raised to the number of positions you moved the decimal point. In this case, it is necessary to move the decimal point 7 positions so, we multiply the number by 10 raised to 7.
Answer: When the air particles inside the balloon become colder, they slow down and do not hit the inside of the balloon as often, so the balloon's volume decreases.
As we know methane is an Alkane to separate an Alkane We use fractional distillation to put each liquid into its fraction with the right temperature group
A. proton donating is often referring to Hydrogen donating in acids. See the extra H+ in common acids: HCl, H2SO4
2.3g of sodium would be needed to create a 100 millimole concentration in one liter.
Given,
Mole of Na+ = 100 millimole
As we know that,
1 millimole = 10 -³ mole
Mole of Na+ in 100 millimoles = 100 × 10 -³ mole
= 0.1mole
<h3>What is Mole? </h3>
Mole is defined as the ratio of mass of Na+ to the molar mass of sodium.
<h3>What is Molar Mass? </h3>
The molar mass is defined as the sum of the total mass in grams unit of the atoms present to make a molecule per mole.
Mole of Na+ = mass of Na + / molar mass of Na +
0.1 = mass of Na + / 22.99 gl mol
Mass of Na + = 0.1 × 22.99
= 2.299 g
Mass of Na + = 2.3 g
Thus, we calculated that 2.3g of sodium would be needed to create a 100 millimole concentration in one liter.
