Explanation:

Reaction rate is a measure of speed of a chemical reaction.

Usually, based on rates, reactions can be divided into two parts:

Slow reactions which usually takes a long time.
Fast reactions which takes place completely in seconds or microseconds.

Reaction rate can be defined as a change in the concentration of a reactant or product per unit time:

The unit is mol dm⁻³ s⁻¹

Reaction rate = $\frac{change in concentration of a reactant and product}{time taken }$

The measurement of the reaction rate is based on the disappearance of a reactant or appearance of a product with increasing reaction time.

What molecule(s) could diffuse across the plasma membrane? question 31 options: disaccharides fe2 tryptophan amino acid ch4

nevsk [136]

The molecule that could diffuse across the plasma membrane is methane (CH4).

<h3>What is diffusion?</h3>

Diffusion is the movement of fluids or substances from regions of high concentration toward regions of lower concentration.

The plasma membrane is the semipermeable membrane that surrounds the cytoplasm of a cell. The semipermeability means that it allows some molecules through but blocks other substances.

The semipermeable plasma membrane readily allows the passage of small hydrophobic and polar molecules.

Therefore, the molecule that could diffuse across the plasma membrane is methane (CH4).

Is the prime meridian a longitudinal or latitudinal line?

Nesterboy [21]

Answer:

longitudinal

Explanation:

A prime meridian is the meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid into two hemispheres.

Hydrogen gas (H2) reacts with oxygen gas (O2) and produces water. If one mol of hydrogen reacts with one mole of oxygen, what is

Amiraneli [1.4K]

HI

So, the formula for water is H2O

When you have the same amount of the reactants , hydrogen will be the limiting reactant.
Limiting reactant is the thing that runs out first.
