Fertilizers have nutrients that help plants grow. Sometimes, when it rains, fertilizers are washed away from farmland into ponds

and lakes. This promotes the growth of algae, a type of plant, present in the water. It is observed that algae grow very fast and cover the surface of the pond completely. They use up all the dissolved oxygen in the pond. How does this affect the other organisms in the pond?
A) They start eating algae.
B) They do not get enough oxygen, and die.
C) They get entangled in the algae, and die.
D) They leave the pond and go to live elsewhere.

Explain why the lattice energy of CaSe is approximately 4 times as large as that of KBr. Check all that apply. Check all that ap
Elza [17]

Answer:

According to Coulomb’s law, the Ca and Se ions have 4 times the attractive force (2+ × 2-) than that of the K and Br ions (1+ × 1-).

Explanation:

From Coulomb's law, the attractive force between calcium and selenium ions is four times the attractive force between potassium and bromide ions.

This has something to do with size and magnitude of charge. Calcium ions and selenide ions are smaller and both carry greater charge magnitude than potassium and bromide ions. This paves way for greater electrostatic attraction between them when the distance of the charges apart is minimal. Hence a greater lattice energy.

A block of wood has the mass of 180 grams.it is 10 cm long,6 cm wide and 4 cm thick.what is it’s density?
DochEvi [55]

Answer:

0.75 g/cm³

Explanation:

Given data:

Mass of wooden block =  180 g

Length of block = 10 cm

Width of block = 6 cm

Height or thickness = 4 cm

Density of block = ?

Solution:

Volume of block = height × length × width

Volume of block = 4 cm × 10 cm× 6 cm

Volume of block = 240 cm³

Density of block:

density = mass/ volume

d = 180 g/ 240 cm³

d = 0.75 g/cm³

A rock weighing 26.0g placed graduated cylinder displacing the volume from 13.12ml to 25.3ml what is the density of the rock in
tia_tia [17]

density = mass /volume

1)mass of rock = 26.0 gram

2)volume of rock = volume of water it has displaced= 25.3-13.12 = 12.18

put the value of mass and volume in first equation and get the density value
