Which substances are present in the net ionic equation for the reaction that would occur when MgCl2 (aq) is combined with H3PO4(aq) ? [Select all that apply.] A H+(aq) B Cl2−(aq) C Mg2+(aq) D Mg+(aq) E Mg3PO4( s) F Mg3(PO4)2(s) G Mg(aq) Cr (aq) H HCl(aq) MgPO4 (s) I Mg2(PO4)3 (s) J H3PO4(aq)

Answers

Answer 1

Answer:

Answer:the correct options are A (H⁺(aq)) and E (Mg₃(PO₄)₂(s)).

Explanation:To determine which substances are present in the net ionic equation for the reaction between MgCl2(aq) and H3PO4(aq), we first need to write the balanced molecular equation and then separate it into ions to identify the spectator ions. Spectator ions are those ions that do not participate in the chemical reaction and remain unchanged.

First, let's write the balanced molecular equation:

MgCl2(aq) + 2H3PO4(aq) -> Mg3(PO4)2(s) + 6HCl(aq)

Now, let's break down the equation into ions:

Mg²⁺(aq) + 2Cl⁻(aq) + 2H₃PO₄(aq) -> Mg₃(PO₄)₂(s) + 6H⁺(aq) + 6Cl⁻(aq)

Now, let's identify the spectator ions, which are the ions that appear on both sides of the equation and do not change:

- Mg²⁺(aq) is present on both sides.

- Cl⁻(aq) is present on both sides.

So, the spectator ions are Mg²⁺(aq) and Cl⁻(aq).

Now, let's determine the substances that are part of the net ionic equation, excluding the spectator ions:

Net Ionic Equation: 2H₃PO₄(aq) -> Mg₃(PO₄)₂(s) + 6H⁺(aq)

From the net ionic equation, the following substances are present:

A. H⁺(aq)

E. Mg₃(PO₄)₂(s)

So, the correct options are A (H⁺(aq)) and E (Mg₃(PO₄)₂(s)).

The other ions and compounds do not participate directly in the net ionic reaction and are spectator ions.

A body moving with a velocity of 20 m/s begins to accelerate at 3 m/s2. How far does the body move in 5 seconds?A. 137.5 m
B. 196 m
C. 260 m
D. 162.5 m

Answers

The distance covered will be:

$d = v_0\cdot t + (1)/(2)a\cdot t^2 = 20(m)/(s)\cdot 5\ s + (5)/(2)(m)/(s^2)\cdot 5^2\ s^2 = \bf 162,5\ m$

The correct answer is D).

During glycolysis, for every 6 moles of glucose that enter the pathway, how many moles of atp are used? how many moles atp are generated? how many moles of nadh are used? how many moles of pyruvate are made?

Answers

During the process of glycolysis 1 mole of glucose yields 2 pyruvic acid. In the process 2 ATPs molecules are used up and 4 other ATP molecules are produced by substrate level phosphorylation and 2 NADH are also produced. Therefore; for six moles of glucose; 12 ATP molecules will be used up, 24 ATP molecules will be generated, 12 moles of NADH will be used and 12 moles of pyruvate are made.

The best tool to use to locate the boundaries between countries is a(n) _____.interrupted area map
political map
population map
relief map

Answers

The correct answer is (b) political map

The explanation:

when a political map: is different than other types of maps because it focuses on government or administrative boundaries rather than geographical or physical features. Instead of showing viewers what exists in the land, it shows those imaginary lines that serve to separate countries, states, territories, and cities. These maps generally include larger bodies of water, such as oceans, rivers, and lakes, as landmarks.

It was made by man not natural like the others maps.

so this is the correct answer.

Final answer:

A political map is the best tool to locate the boundaries between countries, providing distinct and accurate depiction of governmental boundaries.

Explanation:

The best tool to use to locate the boundaries between countries is a political map. Political maps are designed to show governmental boundaries of countries, states, and counties.

They also indicate the location of major cities, and they usually include significant bodies of water.

Unlike other types of maps like interrupted area maps, population maps, or relief maps, a political map focuses specifically on the delineation of imaginary lines separating different political entities, making it the ideal tool for identifying country boundaries.
