Answer:

Dinitrogen tetroxide, commonly referred to as nitrogen tetroxide (NTO), and occasionally (usually among ex-USSR/Russia rocket engineers) as amyl, is the chemical compound N2O4.

Dinitrogen Tetraoxide

Explanation:
Since nitrogen and oxygen are two non metals, they make up a binary covalent compound.

In N2O4, since there is two nitrogen’s, using the chart in the image below we can see that we would use the “di“ prefix (in this case). Since there are 4 oxygen’s we would add the prefix “tetra” as stated in the chart and turn oxygen into oxide; as the rule is add “ide” to the ending of a nonmetal in a binary covalent/ionic compound.

A cart accelerates at 2m/s2 when a force of 60 N is applied. What is the mass of the cart? Formula: F=ma

Fudgin [204]

Answer:

Mass, m = 30 kg

Explanation:

We have,

Acceleration of a cart, $a=2\ m/s^2$

Force applied, is 60 N

It is required to find the mass of the cart.

The formula of the force acting on the cart is :

$F=ma$

m is mass of the cart

$m=\dfrac{F}{a}\\\\m=\dfrac{60\ N}{2\ m/s^2}\\\\m=30\ kg$

So, the mass of the cart is 30 kg.

A chemist reacted 17.25 grams of sodium metal with an excess amount of chlorine gas. The chemical reaction that occurred is show

Afina-wow [57]

Answer: The actual yield of the product is 38.57 g

Explanation:

The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$ ......(1)

We are given:

Given mass of Na = 17.25 g

Molar mass of Na = 23 g/mol

Putting values in equation 1, we get:

$\text{Moles of Na}=\frac{17.25g}{23g/mol}=0.75mol$

For the given chemical reaction:

$2Na+Cl_2\rightarrow 2NaCl$

By stoichiometry of the reaction:

2 moles of Na produces 2 moles of NaCl

So, 0.75 moles of Na will produce = $\frac{2}{2}\times 0.75=0.75mol$ of NaCl

We know, molar mass of $NaCl$ = 58.44 g/mol

Putting values in above equation, we get:

$\text{Mass of NaCl}=(0.75mol\times 58.44g/mol)=43.83g$

The percent yield of a reaction is calculated by using an equation:

$\% \text{yield}=\frac{\text{Actual value}}{\text{Theoretical value}}\times 100$ ......(1)

Given values:

Percent yield of the product = 88 %

Theoretical value of the product = 43.83 g

Plugging values in equation 1:

$88\% =\frac{\text{Actual yield}}{43.83g}\times 100\\\\\text{Actual yield}=\frac{88\times 43.83}{100}=38.57g$

Hence, the actual yield of the product is 38.57 g

Calculate the energy of light having a wavelength of 395 nm. show work

Liono4ka [1.6K]

Answer: $5.032\times 10^{-19}\ J$

Explanation:

Given

The wavelength of the light is $\lambda =395\ nm$

Energy associated with a photon(light) is given by $E=\frac{hc}{\lambda}$

where, $h=\text{Planck constant}$

$c=\text{speed of light}$

$\Rightarrow E=\dfrac{6.626\times 10^{-34}\times 3\times 10^8}{395\times 10^{-9}}\\\\\Rightarrow E=5.032\times 10^{-19}\ J$

Therefore, the energy associated with the light is $5.032\times 10^{-19}\ J$

Liquids do not have the energy to overcome the ___ and move to the gaseous state.

Ugo [173]

Answer - Inter-molecular attractions

Explanation-

As we know everything around us is made up of matter that means everything has molecules as their basic structure. The state of anything is decided by the spaces between the molecules.

The state of the objects that have strong inter-molecular attractions a solid and gradually the lesser will be in state of liquid and gas. The attraction between the molecules is overcome only when a certain amount of energy is provided from outside.
