Well, you can't use this word for word, but a good answer would be something like:
Pesticides release harmful chemicals into the air, not only making it toxic and unsafe for us, but it also has the potential to kill off insects. This affects the ecosystem as well, as it reduces the available food source for larger animals such as birds, which in turn, affect another species.

How many molecules are in 1.95 moles of water?

OLEGan [10]

Water has a molar mass of 18.015 g/mol . This means that one mole of water molecules has a mass of 18.015 g . So, to sum this up, 6.022⋅1023 molecules of water will amount to 1 mole of water, which in turn will have a mass of 18.015 g . 2.7144moles H2O ⋅6.022⋅1023molec.1mole H2O =1.635⋅1024molec.

Consider the substances below.

ratelena [41]

Answer:

They have the same number of atoms. = YES

They have different masses. = YES

Explanation:

1 mol of beryllium

• 1 mol of salt

beryllium = Be = Atomic mass: 9.012182

salt = NaCl = Molar mass: 58.44 g/mol

1 mol of water

• 1 mol of hydrogen

water = H2O = Molar mass: 18.01528 g/mol

hydrogen = H = 1g/mole

Which statement is true about these substances?

They have exactly the same mass. = NO

They have different numbers of particles = NO

They have the same number of atoms. = YES

They have different masses. = YES

Avogadro constant means the number of units in one mole of any substance (defined as its molecular weight in grams) is equal to 6.02214076 × $10^{23}$ .
