Answer:

since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. So as the mass of either object increases, the force of gravitational attraction between them also increases.

Write the word, formula, and chemical equations for the reaction between hydrogen sulfide gas and oxygen gas that produces sulfu

evablogger [386]

Answer:

The balanced equations for the reactions are outlined below:

Explanation:

A balanced equation describes how many (number of moles) atoms of the reactant give rise to how many (number of moles) of product.

Hydrogen sulfide gas ( $H_{2}S$ ) and oxygen gas ( $O_{2}$ ) react to produce sulfur dioxide gas ( $SO_{2}$ ) and water vapor gas.
The balanced equation for the reaction, taking into consideration the states is:

$2H_{2}S(g) + 3O_{2}(g)$ → $2SO_{2}(g) + 2H_{2}O(g)$

Vanadium(II) oxide (VO) is oxidized by iron(III) oxide (Fe2O3) resulting in the formation of vanadium(V) oxide (V2O5) and iron(II) oxide (FeO).

The balanced equation:

$2VO + 3Fe_{2}O_{3}$ → $V_{2} O_{5} + 6FeO$

Which of the following elements will form a cation with a +2 charge?

suter [353]

Cations (positively-charged ions) and anions (negatively-charged ions) are formed when a metal loses electrons, and a nonmetal gains those electrons. The electrostatic attraction between the positives and negatives brings the particles together and creates an ionic compound, such as sodium chloride

Which flow chart is accurate?

djverab [1.8K]

Answer:

<em>The correct option is A) DNA → RNA → protein</em>

Explanation:

Central Dogma can be described as the process under which the processes of transcription and translation are focused. It is the process by which particular parts of DNA or particular genes make up the specified proteins which are required.

The conversion of DNA into RNA is known as transcription. This process occurs in the nucleus. The conversion of mRNA into proteins is termed as translation. This process occurs in the ribosomes of the cytoplasm.

Density = Mass over Volume

D = m/V

<h3>Explanation:</h3>

<u>Step 1: Define</u>

D = 25 g/cm³

m = 100 g

<u>Step 2: Solve for </u><em><u>V</u></em>

Substitute variables [D]: $\displaystyle 25 \ g/cm^3 = \frac{100 \ g}{V}$
Multiply <em>V</em> on both sides: $\displaystyle V(25 g/cm^3) = 100 \ g$
Isolate <em>V</em>: $\displaystyle V = 4 \ cm^3$
