Answer:

Prophase I

Sorry if wrong I was rushing !!

Answer:

he substance with more intermolecular attraction will be having higher melting point. So higher the melting point,higher the force of attraction will be

Explanation:

Melting point is the minimum temperature at which a substancr start to melt.As melting happens the particles force of attraction will be lowering.Substance which have higher force of attraction,

It will take a little time to reach the melting point because the particles does not move due to its force of attraction. When required heat energy is supplied it starts to melt..

Hope this helps....

Answer:

Violet is scattered most by Earth's atmosphere, but the blue cones in our eyes aren't as sensitive to it. While our red cones aren't good at seeing blue or violet light, they are a bit more sensitive to violet than our green cones.

Answer:

squeezing a stress ball

Explanation:

Think of compression as reducing the amount of space something takes up. When you squeeze a stress ball, it gets smaller or deformed and the amount of space it takes up gets smaller.

Answer:

Third one

Explanation:

Answer:

T° Freezing solution = - 2.91°C

Explanation:

To solve this, we apply this formula:

ΔT = Kf . m . i

Our solute is SnI₄

ΔT = Freezing T° of pure solvent - Freezing T° of solution

m is molality

i, numbers of ions dissolved.

SnI₄ →  Sn⁴⁺  +  4I⁻

5 moles of ions have been formed, 1 mol of Sn⁴⁺ and 4 moles of iodide.

Let's determine molality. Firstly we need the moles of salt.

235 g . 1mol / 626.3 g = 0.375 moles

molality = mol /kg of solvent → 0.375 mol /1.20kg = 0.313 m

Kf reffers to Cryoscopic constant, for water is 1.86°C/m. We replace data at formula →  0°C - T°F solution = 0.313 m . 1.86°C/m . 5

T°F solution = - 2.91°C

Answer:

Los habitantes del planeta con una atmósfera superior a 5,1 atm de la Tierra, no estarían nadando en ríos de dióxido de carbono líquido

Explanation:

De las tablas de datos termodinámicos, la presión a la que el vapor de dióxido de carbono está en equilibrio con su estado líquido a una temperatura ambiente de 25 ° C es 6,401 kPa, lo que equivale a 63,17296 atm.

Por lo tanto, a una presión de 5.1 de la atmósfera terrestre, el dióxido de carbono es completamente gaseoso y los habitantes del planeta con una presión atmosférica de 5.1 atm de la Tierra todavía observarían solo hidrógeno gaseoso y no estarían nadando en ríos de dióxido de carbono líquido.

Mammals will shed much of their fur or hair to help them cool off and maintain  their body temperature.

Answer:

the answer is B

Explanation:

Answer:

pH = 10.75

Explanation:

To solve this problem, we must find the molarity of [OH⁻]. With the molarity we can find the pOH = -log[OH⁻]

Using the equation:

pH = 14 - pOH

We can find the pH of the solution.

The molarity of Ca(OH)₂ is 2.8x10⁻⁴M, as there are 2 moles of OH⁻ in 1 mole of Ca(OH)₂, the molarity of [OH⁻] is 2*2.8x10⁻⁴M = 5.6x10⁻⁴M

pOH is

pOH = -log 5.6x10⁻⁴M

pOH = 3.25

pH = 14-pOH

Answer:

0.025 L

Explanation:

The production of oxygen in the electrolysis of water is;

4OH^-(aq) -----> 2H2O(l) + O2(g) + 4e

Since 1 F = 96500C

molar volume of a gas = 22.4 L

From the reaction equation;

4 * 96500 C yields 22.4 L of oxygen

(3 * 60 * 60 *  0.0400) C yields (3 * 60 * 60 *  0.0400) * 22.4/4 * 96500

= 9676.8/386000

= 0.025 L

Explanation:

Since, the boulder is at rest. This means that there is an equilibrium of forces acting on the boulder.

According to principle of equilibrium of forces a body can be in position of rest only when net force acting on body is zero for translation equilibrium and net moment acting on the body must also be zero for rotational equilibrium.

Therefore, net forces and net moment acting on the boulder is zero.

Answer:

5.46

Explanation:

From the question,

pH this can be defined as the acidity or alkalinity of a solution.

The expression for pH is given as

pH = -log(H⁺)...................... Equation 1

Where H⁺ = Hydrogen ion of HCL

Given: H⁺ = 3.5×10⁻⁶ M

Substitite this value into equation 1

pH = -log(3.5×10⁻⁶)

pH = 5.46

Hence the pH of HCl is 5.46
