A35.00ml sample of naoh solution is titrated to an endpointby
14.76 ml 0.4122m hbr solution. what is the molarity of themolarity
of the naoh solution.

0.1738 M

Explanation:

Let's consider the neutralization reaction between NaOH and HBr.

NaOH + HBr → NaBr + H₂O

The moles of HBr are:

14.76 × 10⁻³ L × 0.4122 mol/L = 6.084 × 10⁻³ mol

The molar ratio of NaOH to HBr is 1:1. In the endpoint, they have reacted completely, so the moles of NaOH were 6.084 × 10⁻³ mol before the reaction.

The molarity of NaOH is:

M = 6.084 × 10⁻³ mol / 35.00 × 10⁻³ L = 0.1738 M

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
