Answer:

1038.96 kPa

Explanation:

We’ll use the ideal gas law; P1V1/T1 = P2V2/T2

P1*14.8/75.5 = 101.3*16.5/70.2

P1 = (101.3 * 16.5 * 75.5) / (70.2 *14.8)

P1 = 1038.96

Explain how our body systems work together to get oxygen into and around our body. Answer must be three sentences long
sashaice [31]

Inhales. Oxygen - good for the body - gives it to the Circulatory System to be transported throughout the body through the blood. Digestive System gets nutrients from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go.

I hope this helps! :')

Calculate the thermometer in an air-conditioned room reads 20.0°C what is the temperature of the room In degrees Fahrenheit and
maks197457 [2]

Answer:

A. 68°F

B. 293K

Explanation:

The temperature (celsius) = 20.0°C

A. Conversion of the temperature in celsius to fahrenheit.

This is illustrated below:

°F = 9C/5 + 32

C = 20°C

°F = 9C/5 + 32

°F = 9x20/5 + 32

°F = 36 + 32

°F = 68°F

B. Temperature (Kelvin) = temperature (celsius) + 273

Temperature (celsius) = 20°C

Temperature (Kelvin) = 20°C + 273

Temperature (Kelvin) = 293K

Hclo is a weak acid (ka=4.0x10^-8) and so the salt naclo acts as a weak base. what is the ph of a solution that is 0.037 m in na
ankoles [38]

<u>Given:</u>

Concentration of NaClO = 0.037 M

ka (HClO) = 4.0*10⁻⁸

<u>To determine:</u>

The pH of the NaClO solution

<u>Explanation:</u>

The hydrolysis of the weak base can be represented by the ICE table shown below-

                ClO-      +     H2O    ↔    HClO    +       OH-

Initial        0.037M                              0                    0

Change         -x                                 +x                  +x

Equilibrium  (0.037-x)                        x                     x

kb  = kw/ka =  [HClO][OH-]/[ClO-]

10⁻¹⁴/4*10⁻⁸ = x²/(0.037-x)

x = [OH-] = 9.62*10⁻⁵

p[OH-] = -log[OH-] = -log [9.62*10⁻⁵] = 4.02

pH = 14-p[OH-] = 14 - 4.02 = 9.98

Ans: pH of the solution is 9.98
