How reactive is an atom of Sodium(Na) and why? Question 1 options: Sodium (Na) is very reactive because it does not have a full

pentagon [3]

I'm pretty sure the answer is the first one. The fact that it doesn't have a full valence shell means that electrons from other atoms can react and bond with the sodium atom.
Hope this helps x

Describe what happens when ionic and covalent (molecular) substances dissolve. Fill in the blanks using the options below:covale

Lena [83]

1. ionic compound , aqueous cations and aqueous anions

2. covalent compound aqueous covalent compound

Explanation:

1. A(n) ionic compound dissolves in water , H₂O(l), will produce aqueous cations and aqueous anions in solution.

When NaCl dissolves in water it will produce Na⁺ and Cl⁻ ions in solution

2. A(n) covalent compound  dissolves in water , H₂O(l), will produce aqueous covalent compound in solution.

When Ammonia (NH₃) dissolves in water it forms aqueous ammonia, NH₃(aq)

Organic compounds, like carbohydrates, proteins, nucleic acids, and lipids, are all good examples of covalent compounds.

A horse runs 1 km in 15 s. What is the average speed

Reptile [31]

The average speed of the horse for the entire motion is 66.67 m/s.

The given parameters;

distance traveled by the horse, d = 1 km = 1,000 m
time of motion of the horse, t = 15 s

The average speed of the horse is calculated by dividing the total distance traveled by the horse by the time of motion.

The average speed of the horse is calculated as follows;

$average\ speed = \frac{distance}{time} \\\\average\ speed = \frac{1000 \ m}{15 \ s} = 66.67 \ m/s$

Thus, the average speed of the horse for the entire motion is 66.67 m/s.

A car can accelerate from a standstill to 100 km/h [E] in 9.60s. calculate the average acceleration

Lelu [443]

Answer:

Acceleration is :

a = 2.89 m/s2

Explanation:

Acceleration : It is the change in the velocity of the object per unit time.

The object starts from the rest , so the initial velocity of the object is zero.

Initial velocity , u = 0

Final velocity = 100 km/h

Change the velocity to m/s because[ time unit is in second(9.60 s)]

1 km = 1000 m

1 hour = 60 x 60 sec = 3600 sec

$1km/h=\frac{1000}{3600}m/s$

$1km/hr=\frac{5}{18}$

$100km/hr=\frac{5}{18}\times 100$

$v=\frac{5}{18}\times 100$

v = 27.78 m/s

u = 0 m/s

time = 9.60 s

The acceleration"a" is calculated using :

$a=\frac{v-u}{t}$

$a=\frac{27.78-0}{9.6}$

$a=\frac{27.78}{9.6}$

$a=2.89m/s^{2}$
