Goal of the planned mission MIRI is "to explore the Kupier Belt".

Explanation:

MIRI, Mid-infrared Instrument, was designed to play an important role in NASA's "James Webb Space Telescope"(JWST).This is a joint project involving the Space Agency Europe and Canada. This telescope is designed to bring the images of stars and galaxies in infrared light. This grasps a wavelength of 5 to 28 microns. It also has a sensitive dectector allowing to see the red shifted light, stars that are newly formed and the comet that are blur.

Also, to explore the Kuiper belt that is located in the outer solar system that extends from the Neptune to sun. It is believed to be similar to asteroid belt but 20 times broad and 200 times massive than it.

A 0.1014 g sample of a purified compound containing C, H, and, O was burned in a combustion apparatus and produced 0.1486 g CO2

Alina [70]

Answer: The empirical formula for the given compound is $CH_2O$

Explanation:

The chemical equation for the combustion of hydrocarbon having carbon, hydrogen and oxygen follows:

$C_xH_yO_z+O_2\rightarrow CO_2+H_2O$

where, 'x', 'y' and 'z' are the subscripts of Carbon, hydrogen and oxygen respectively.

We are given:

Mass of $CO_2=0.1486g$

Mass of $H_2O=0.0609g$

We know that:

Molar mass of carbon dioxide = 44 g/mol

Molar mass of water = 18 g/mol

For calculating the mass of carbon:

In 44 g of carbon dioxide, 12 g of carbon is contained.

So, in 0.1486 g of carbon dioxide, $\frac{12}{44}\times 0.1486=0.0405g$ of carbon will be contained.

For calculating the mass of hydrogen:

In 18 g of water, 2 g of hydrogen is contained.

So, in 0.0609 g of water, $\frac{2}{18}\times 0.0609=0.00677$ of hydrogen will be contained.

Mass of oxygen in the compound = (0.1014) - (0.0405 + 0.00677) = 0.054 g

To formulate the empirical formula, we need to follow some steps:

Step 1: Converting the given masses into moles.

Moles of Carbon = $\frac{\text{Given mass of Carbon}}{\text{Molar mass of Carbon}}=\frac{0.0405g}{12g/mole}=0.003375moles$

Moles of Hydrogen = $\frac{\text{Given mass of Hydrogen}}{\text{Molar mass of Hydrogen}}=\frac{0.00677g}{1g/mole}=0.00677moles$

Moles of Oxygen = $\frac{\text{Given mass of oxygen}}{\text{Molar mass of oxygen}}=\frac{0.054g}{16g/mole}=0.003375moles$

Step 2: Calculating the mole ratio of the given elements.

For the mole ratio, we divide each value of the moles by the smallest number of moles calculated which is 0.485 moles.

For Carbon = $\frac{0.003375}{0.003375}=1$

For Hydrogen = $\frac{0.00677}{0.003375}=2.00\times 2$

For Oxygen = $\frac{0.003375}{0.003375}=1$

Step 3: Taking the mole ratio as their subscripts.

The ratio of C : H : O = 1 : 2 : 1

The empirical formula for the given compound is $C_1H_2O_1=CH_2O$

Thus, the empirical formula for the given compound is $CH_2O$

How is Deposition a exothermic reaction?

nikdorinn [45]

<span>all the ones that phase down are exothermic - freezing, deposition, condensation.

all the ones that phase up are endothermic - melting, sublimation, vaporization

endothermic is to gain heat, exothermic is to release heat</span>

A substance with a pH value of 8.0 and [H3O+] of 1.00 x 10-8 would be a basic substance.

garik1379 [7]

False

if the pH is 8, this is basic because based on the pH scale, any below 7 is acidic, above 7 is basic and at 7 is neutral.

The molar solubility of cui is 2. 26 × 10-6 m in pure water. Calculate the ksp for cui.

nataly862011 [7]

Ksp(the solubility product constant) = [Cu⁺] [I⁻]

So, the Ksp for Cui would be:

Ksp = (2.26 × 10⁻⁶) (2.26 × 10⁻⁶) = 5.11 x 10⁻¹²

<h3 />

Formula used:

K = $K_{sp} = [A^+]^a [B^-]^b$ , where

Ksp = solubility product constant

A⁺ = cation in an aquious solution

B⁻ = anion in an aqueous solution

a, b = relative concentrations of a and b

<h3><u>Definition</u></h3>

The equilibrium constant for a solid material dissolving in an aqueous solution is the SOLUBILITY PRODUCT CONSTANT, Ksp. It stands for the degree of solute dissolution in solution. A substance's Ksp value increases with how soluble it is.

Take into account the general dissolving response (in aqueous solutions) below:

aA(s)⇔cC(aq)+dD(aq)

The molarities or concentrations of the products (cC and dD) must be multiplied in order to find the Ksp. Any product that has a coefficient in front of it must be raised to the power of that coefficient (and also multiply the concentration by that coefficient).
