<u>Answer:</u> The correct answer is 4-7.

<u>Explanation:</u>

A non-metal is defined as the element which gains electron to attain stable electronic configuration and to attain a negative ion which is anion.

X+ne^-\rightarrow X^{n-}

Non-metals are the elements which belong to Group 14 to Group 17.

The valence electronic configuration of the elements:

  • Belonging to Group 14 = ns^2np^2

Number of valence electrons = 4

  • Belonging to Group 16= ns^2np^3

Number of valence electrons = 5

  • Belonging to Group 16 = ns^2np^4

Number of valence electrons = 6

  • Belonging to Group 17 = ns^2np^5

Number of valence electrons = 7

Hence, the correct answer is 4-7.

1. 90.0 mL of distilled water is added to a 10.0mL sample of 0.150mol/L sodium
aniked [119]

Answer: dilute

Explanation:

A concentrated solution which is used to prepare solutions of lower concentrations by diluting it with addition of water.

A dilute solution is one which contains lower concentration.

Using Molarity equation:

M_1 =concentration of stock solution = 0.150 mol/L

V_1 = volume of stock solution = 10.0 ml

M_2 = concentration of dilute solution = ?

V_2 = volume of dilute solution = (10.0+90.0) ml = 100.0 ml

0.150\times 10.0=M_2\times 100.0

M_2=0.015mol/L

As the concentration is less than the original concentration, the solution is termed as dilute.

A block of aluminum with a mass of 140 g is cooled from 98.4°C to 62.2°C with a release of 4817 J of heat. From these data, calc
disa [49]

Answer:

specific heat = 0.951 j/g·°C

Explanation:

Heat flow equation  => q = m·c·ΔT

q = heat flow = 4817 joules

m = mass in grams = 140 grams Aluminum

c = specific heat = ?

ΔT = Temperature Change in °C = 98.4°C - 62.2°C = 36.2°C

q = m·c·ΔT => c = q/m·ΔT = 4817j/(140g)(36.2°C) = 0.951 j/g·°C
