What is the chemical name of the compound Cu2CO3?

Answers

Answer 1

Answer:

Answer:

Copper (I) carbonate or cuprous carbonate.

Explanation:

Hello,

In this case, by considering the given formula, we identify the copper's oxidation state as +1 since the carbonate anion is -2 and copper's subscript is 2, therefore +1 is its oxidation state. On the other hand, carbon's oxidation state in CO₃⁻² is +4, that is why according to the IUPAC rules, its name is carbonate. Thus, one sums up that the chemical name of the given compound is copper (I) carbonate or cuprous carbonate.

Best regards.

Answer 2

Answer: Copper(l) Carbonate

which part of earths interior is inferred to have convection currents that causes tectonic plates to move

Answers

Asthenosphere is inferred to have convection currents that cause tectonic plates to move because the material in this part of the mantle flows and can move plastically and convection is all about the movement of the magma,the hotter stuff rising towards the crust while the cooler stuff sinks deeper into the mantle.

Answer:

Correct answer: B). Global climate is changing due to burning of fossil fuels and deforestation.

Forest holds a large amount of carbon, plants are known to absorb carbon dioxide from the atmosphere as they grow, that carbon dioxide is stored in plants in the form of carbon in plant's roots, leaves and in the soil. When trees are cut down, that stored carbon is released in the environment in the form of carbon dioxide, which accounts for approximately 18% of global greenhouse gas emission.

The burning of fossil fuel like coal, petroleum, oil, gas for the energy purpose is one of the major contributors for the rising level of carbon dioxide in the atmosphere, which leads to global warming and affect the climate.

Hence, the correct answer would be option B.

As a consequence of the discovery of the nucleus by rutherford, which model of the atom is thought to be true? a. electrons are distributed around the nucleus and occupy almost all the volume of the atom.
b. protons, electrons and neutrons are evenly distributed throughout the volume of the atom.
c. the nucleus is made of electrons and protons

Answers

Electrons are distributed in shells revolving around the nucleus and occupy almost all the volume of the atom.

In the nucleus of an atom, proton and neutron are present whereas electrons are present in shells revolving around the nucleus. Most of the volume of an atom has empty spaces in which shells are present in which electrons are moving.

The number of protons and electrons are the same in an atom but the number of neutrons are different so we can conclude that electrons are distributed in shells that are present around the nucleus.

calculate the mass required to prepare 2.5 L of 1.0 M NaOH solution. Given that the molar mass for NaOH is 40 g/mol.

Answers

Answer:

$100\; \rm g$ of ${\rm NaOH}\; (s)$ would be required.

Explanation:

The quantity of solute in a solution of concentration $c$ and volume $V$ would be $n = c \cdot V$ .

It is given that volume $V = 2.5\; \rm L$ for the solution in this question. It is also given that the concentration of the $\rm NaOH$ solute in this solution is $c = 1.0\; \rm M$ , which is the equivalent to $c = 1.0\; \rm mol \cdot L^(-1)$ .

Apply the equation $n = c \cdot V$ to find the quantity of $\rm NaOH$ in this solution:

$\begin{aligned}n &= c \cdot V \n &= 1.0\; \rm mol \cdot L^(-1) * 2.5\; \rm L \n &= 2.5\; \rm mol\end{aligned}$ .

Multiply the quantity $n$ of $\rm NaOH$ in this solution with the formula mass $M$ of ${\rm NaOH}\!$ to find the corresponding mass:

$\begin{aligned}m &= n \cdot M \n &= 2.5\; \rm mol * 40\; \rm g \cdot mol^(-1) \n &= 100\; \rm g\end{aligned}$ .

Thus, this solution would contain $100\; \rm g$ of ${\rm NaOH}$ .

It would thus take $100\; \rm g$ of ${\rm NaOH}$ to prepare this solution.

Answer:

The required mass to prepare 2.5 L of 1.0 M NaOH solution is 100 g

Explanation:

We do this by preparing the equation:

Mass = concentration (mol/L) x volume (L) x Molar mass

Mass = 1.0 M x 2.5 L x 40 g/mol

Mass = 100 g

Which step would help a student find the molecular formula of a compound from the empirical formula?Multiply the ratio of the actual mass of the compound to the empirical formula mass by the subscripts of the empirical formula.

Subtract the ratio of the actual mass of the compound to the empirical formula mass from the subscripts of the empirical formula.

Divide the ratio of the actual mass of the compound to the empirical formula mass by the subscripts of the empirical formula.

Add the ratio of the actual mass of the compound to the empirical formula mass to the subscripts of the empirical formula.

Answers

Answer : Option A) Multiply the ratio of the actual mass of the compound to the empirical formula mass by the subscripts of the empirical formula.

Explanation : To find molecular formula for a compound one needs to follow the below steps using the emphirical formula of that compound.

Step 1) Calculate the empirical formula mass of that compound

Step 2) Take the ratio of gram molecular mass by the empirical formula mass that was obtained in step 1.

Step 3) Multiply each of the subscripts within the empirical formula by the number that is calculated in step 2.

By following these easy steps one can find the molecular formula.

The step that would help a student finds the molecular formula of a compound from the empirical formula is by ‘Multiply the ratio of the actual mass of the compound to the empirical formula mass by the subscripts of the empirical formula.’
