Answer:
mass spectrometer
Explanation:
The masses of atoms and molecules can be measured using an instrument called mass spectrometer. This instrument can be used to also measure their relative concentrations. The mass spectrometer functions using the magnetic force that is applied on a charged particle that is in motion.
Answer:
H2 + I2 —> 2HI
Explanation:
H2 + I2 —> HI
Now, let us balance the equation. This can be achieved by doing the following:
There are 2 atoms of H on the left side of the equation and 1atom on the right side. It can be balance by putting 2 in front of HI as shown below:
H2 + I2 —> 2HI
Now the equation is balanced as there are equal numbers of atoms of the different elements present on both sides of the equation.
is a carbon oxoacid and a chalcocarbonic acid. It has a role as a mouse metabolite. It is a conjugate acid of a hydrogencarbonate. Bicarbonate, or hydrogen carbonate, is a simple single carbon molecule that plays surprisingly important roles in diverse biological processes.
Answer:
B. Carry oxygen, nutrients, waste, & to fight pathogens
Explanation:
The circulatory system refers to all organs and tissues involved in carrying blood and lymph around the body.
The circulatory system carries oxygenated blood from the heart to cells and deoxygenated blood back to the heart.
Nutrients are carried in the blood to cells in different parts of the body and waste products are also carried from cells in the blood.
White blood cells is a component of blood in the circulatory system that fights off diseases.
