Answer:

The fourth one.

Explanation:

The fourth graph shows an object speeding up ( accelerating ) coz the velocity (tangent at the curve ) at every point is different, hence denoting an acceleration.

The human body needs at least 1.03 x 10-^2 mol O2 every minute. If all of this oxygen is used for the
Neko [114]
<h3>Answer:</h3>

0.3093 g of glucose are consumed each minute by the body.

<h3>Explanation:</h3>
  • During cellular respiration glucose is broken down in presence of oxygen to yield energy, water and carbon dioxide.
  • The equation for the reaction taking place during cellular respiration is;

C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂

We are required to calculate the amount of glucose in grams;

<h3>Step 1: Calculate the moles of glucose broken down</h3>

From the equation, the mole ratio of glucose to Oxygen is 1 : 6

Moles of Oxygen in a minute is 1.03 × 10^-2 moles

Therefore, moles of glucose will be;

= (1.03 × 10^-2)÷6

= 1.717 × 10^-3 moles

<h3>Step 2: Mass of glucose </h3>

Mass is given by multiplying the number of moles with molar mass

mass = moles × molar mass

Molar mass glucose is 180.156 g/mol

Therefore;

Mass = 1.717 × 10^-3 × 180.156 g/mol

         = 0.3093 g

Hence, 0.3093 g of glucose are consumed each minute by the body.

A set of aqueous solutions are prepared containing different acids at the same concentration: acetic acid, chloric acid and hydr
navik [9.2K]

Answer:

The solutions of hydrobromic acid and of chloric acid are the most electrically conductive.

Explanation:

The electrical conductivity of a solution is determined by the concentration of ions in the solution. The acids listed react with water to form ions. In the case of hydrobromic acid, for example, the reaction is as follows:

HBr + H2O >> H3O(+) + Br(-)

Hydrobromic acid and chloric acid are strong acids, meaning the reaction is considered to proceed at 100%. Acetic acid, however, is a weak acid and the reaction with water does not go to completion, so there are less ionic species in the solution of acetic acid, which makes it less electrically conductive.

A chemist pours 1 mol of zinc granules into one beaker and 1 mol of zinc chloride powder into another beaker. What do the two sa
Oksana_A [137]
Answer is: <span> two samples have in common same amount of substance and same number of particles.
1) There are same amount of substance in both beakers:
n(Zn) = 1 mol.
n(ZnCl</span>₂) = 1 mol.
2) There are same number of particles (atoms, molecules, ions) in both beakers:
N(Zn) = n(Zn) · Na.
N(Zn) = 1 mol · 6.023·10²³ 1/mol = 6.023·10²³ atoms of zinc.
N(ZnCl₂) = n(ZnCl₂) · Na.
N(ZnCl₂) = 1 mol · 6.023·10²³ 1/mol = 6.023·10²³ molecules of zinc(II) chloride.
Na - Avogadro number.

¿Qué establece la ley de la conservación de la materia? Explicar.
masya89 [10]

La materia no se crea ni se destruye solo se transforma

Explanation:

«En toda reacción química la masa se conserva, es decir, la masa total de los reactivos es igual a la masa total de los productos».

Los átomos ni de crean ni se destruyen,durante una reacción química.Por lo tanto una ecuación química ha de tener el mismo numero de atomos de cada elemento a ambos lados de la flecha. Se dice entonces que la ecuación esta balanceada

Espero y te sirva!!
