Answer:

gas and liquid

Explanation:

A liquid is obviously a fluid, as a gas can be partaken as a fluid as it can have the volume to shape and fill a container a fluid can as well.

Explanation:cell division occurs to produce new cells from preexisting ones. the new cells are called daughter cells.the old cells are called parent cells.cell division may be mitosis or meiosis. Mitosis occurs in a somatic cell and produce four daughter cell. Meiosis occurs in sex cells and produce two daughter cells. Cell division usually involves Prophase, metaphase, anaphase and telophase.

Cell division occurs to ensure the continous existence of life.

Mitosis involve producing daughter cells with the same number of chromosomes as the parent cells while meiosis involves producing daughter cells with Half number of chromosomes.

What mass of H₂ is needed to react with 8.75 g of O₂ according to the following equation: O2(g) + H2(g) → H₂O(g)?

FromTheMoon [43]

Explanation:

For reacting with 8.75 grams of oxygen, 1.08 grams of hydrogen is required.

The given balanced equation has been:

\rm O_2\;+\;2\;H_2\;\rightarrow\;H_2OO2+2H2→H2O

From the equation, 1 mole of oxygen reacts with 2 mole of hydrogen to give 1 mole of water.

The mass of oxygen has been: 8.75 g,

Moles = \rm \dfrac{weight}{molecular\;weight}molecularweightweight

Moles of oxygen = \rm \dfrac{8.75}{32}328.75

Moles of oxygen = 0.27 mol

Since,

1 mole Oxygen = 2 mole hydrogen

0.21 mol oxygen = 0.54 mol hydrogen

Mass of hydrogen = moles \times× molecular weight

Mass of hydrogen = 0.54 \times× 2

Mass of hydrogen = 1.08 grams.

Thus, for reacting with 8.75 grams of oxygen, 1.08 grams of hydrogen is required.

Whic number of the periodic table is the atomic number and which number is the atomic mass?

Anettt [7]

Answer:

The mass number (represented by the letter A) is defined as the total number of protons and neutrons in an atom. Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus.

The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of carbon with six neutrons, carbon-12, has an atomic mass of 12 amu.

Given the reaction for the nickel-cadmium battery: 2NiOOH + Cd +2H2O -> 2Ni(OH)2 + Cd(OH)2 What species is oxidized during th

jok3333 [9.3K]

Answer:

Cd is oxidized during the discharge of the battery

Explanation:

Based on the reaction:

2 NiOOH + Cd + 2H₂O → 2Ni(OH)₂ + Cd(OH)₂

And knowing Oxygen and hydrogen never change its charge, we must to find oxidation state of Ni and Cd before and after the reaction:

In NiOOH: 2 O = -2*2 = -4 + 1H = +1, = -4 + 1 = -3. And as the molecule is neutral, Ni is 3+

In Ni(OH)₂: OH = -1. As there are 2 OH = -2. That means Ni is +2

The Ni is gaining one electron, that means is been reduced

Cd before reaction is as pure solid with oxidation state = 0

Cd after the reaction is as Cd(OH)₂: 2 OH = -2. That means Cd is +2

The Cd is loosing 2 electrons, that means is the species that is oxidized.
