Which takes longer to orbit the Sun: Mars or Jupiter?

Answer:

Water and Salts

Explanation:

Because a neutralization reaction, which results in the formation of salt and water, occurs when an acid and a base react with one another. The H + ions from the acid and the OH - ions from the base combine to form water. As a result of the reaction, a solution with a neutral pH (pH = 7) is produced as the strong acids and strong bases completely dissociate.

The oxidation number for sulphur (S) in the given compound sulphur trioxide (SO₃) is +6.

Oxidation number of any element is define as the number of exchangeable electrons from the outermost shell of an element.

For the given compound SO₃ no charge is present on the whole molecule and oxidation state of oxygen atom is -2, and let we assume that the oxidation state of sulphur atom is x and we calculate for x as:

x + 3(-2) = 0

x - 6 = 0

x = +6

Hence the oxidation state of atom is +6.

Answer:A solar flare is an intense burst of radiation coming from the release of magnetic energy associated with sunspots. Flares are our solar 

Explanation:

Answer:

V1/T1 = V2/T2 (Charles' Law)

T is in Kelvin. Celsius temp plus 273.15 = K

T1 = 14 +273

= 287 K

T2 = 29 + 273

= 303 K

4.5 / 287 = V2 / 303

V2 = 4.75 L

= 4.8 L

The equation that has been the representation of the net ionic equation has been Upper H superscript plus, plus upper O upper H superscript minus right arrow upper H subscript 2 upper O.  

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products.

The balanced chemical equation for the reaction has been:

[tex]\rm Mg(OH)_2+2HNO_3-- > Mg(NO_3)_2+H_2O[/tex]

The net ionic equation has been given as the ionic form of the reactants and product that has been formed in the reaction. The ions same on the product and reactant side of the equation has been eliminated in the net ionic equation.

The net ionic equation for the given chemical reaction has been:

[tex]\rm Mg^{2+}+OH^++2H^++2NO^{-}_3-- > Mg^{2+}+NO^{-}_3+2H_2O\\\\OH^{-}+2H^+-- > 2H_2O[/tex]

The equation that has been the representation of the net ionic equation has been Upper H superscript plus, plus upper O upper H superscript minus right arrow upper H subscript 2 upper O.  Thus, option A is correct.

Answer:

9.7 × 10² g NaF.

Explanation:

Molarity is defined by the amount of solute (mols) over the volume of solution (liters):

[tex]\displaystyle \text{Molarity} = \frac{\text{mols solute}}{\text{L solution}}[/tex]

We want to create 6.3 liters of a 3.6 molar solution of NaF.

Solve for the amount of NaF necessary:
[tex]\displaystyle \begin{aligned} (3.6\text{ M}) & = \frac{\text{ mol NaF}}{6.3\text{ L}} \\ \\ \text{mol NaF} & = 23 \text{ mol}\end{aligned}[/tex]

Therefore, about 23 moles of NaF is required.

Convert from moles to grams. The molecular weight of NaF is 41.99 g/mol:
[tex]\displaystyle 23\text{ mol NaF} \cdot \frac{41.99\text{ g NaF}}{1\text{ mol NaF}} = 9.7\times 10^2\text{ g NaF}[/tex]

Therefore, about 970 grams of NaF is needed to create the solution.

Answer: Heyo Kenji Here! Here's your answer- In addition, since the external battery source is what drives the electrons through the circuit, the electrodes will match the positive and negative terminal of the battery. While the anode remains the site of oxidation, it becomes the positive terminal, and the cathode becomes the negative terminal.

Explanation: Hope this helps!

Have a nice day!
- Kenji ^^

Answer: In a galvanic (voltaic) cell, the anode is considered negative and the cathode is considered positive. This seems reasonable as the anode is the source of electrons and cathode is where the electrons flow. However, in an electrolytic cell, the anode is taken to be positive while the cathode is now negative.

Answer:

[Sr2+][CO32-]

Explanation:

When this compound dissolves in water, it breaks up into Sr cations and CO3 anions. Due to the fact that the element Sr lies in group 2, and is a cation, we know that it can be represented by the expression - [Sr2+]. From this we can come up with the following expression for CO3 - [CO32-].

In the given reaction, the substance that is the base of the reaction is [tex]CaSO_4[/tex]. The correct option is C.

The base is a slippery liquid that is bitter and turns red litmus paper to blue.

Bases react with acids to form salts.

Then bases have pH above 7.

Examples of bases are calcium carbonate, sodium hydroxide, etc.

Thus, the correct option is C.

Based on temperature changes, the phase changes that occur in water is from a solid at A to a liquid at B, and from liquid a B to gas at C.

Change of state is the process whereby a substance changes its state of matter from one form to another as as result of heat changes.

In the graph shown above, water exists in three states at different points.

Therefore, the phase changes that occur in water is from a solid at A to a liquid at B, and from liquid a B to gas at C.

The proper way to balancing the given equation is 3Ca(OH)₂+2H₃PO₄→Ca₃(PO₄)₂ +6H₂O

Balanced equations are those reactions in which each atom of reactants and products are present in same quantity on both sides of the equation.

Given chemical reaction is:
Ca(OH)₂ + H₃PO₄ → Ca₃(PO₄)₂ + H₂O

Let we discuss each given reaction to get the perfectly balanced equation:

In the above reaction number of hydrogens, calcium as well as of oxygens are not equal so that it is an unbalanced equation.

In the above equation all atoms are present in equal amount on both sides of the reaction, so that it is a balanced equation.

In the above reaction number of oxygen and hydrogen atoms are not equal so that the given equation is an unbalanced one.

In the above freaction all atoms are unequal so that given equation is an unbalanced equation.

Hence balanced equation is 3Ca(OH)₂ + 2H₃PO₄ → Ca₃(PO₄)₂ + 6H₂O.
