WARMING OCEAN TEMPERAUTRE AFFECTS THE BIODIVERSITY OF ORGANISMS. WHICH OF THE FOLLOWING DISRUPTIONS WOULD YOU EXPECT TO SEE IN A
Ilya [14]

Climate change greatly affects the community of whales and dolphins. Most of the species of whales live in a specific temperature range, because of the non-availability of their food, zoo plankton in warm waters. One of the most important organisms whales prey up on are zoo plankton, whose number declined greatly due to the warming of oceans. These whales migrate to Northern waters overcome the effects of increasing temperature and in search of food. So ,we can expect a disruption in the food chain as a result of the warm oceanic waters.

Which statement explains why the bonds between nonmetals tend to be covalent? The bonds are found to be nondirectional. They hav
Alexandra [31]
Correct Answer: <span>They have small differences in electronegativity (statement 3)
Reason: 
The nature of chemical bond between atoms is primarily driven by the electronegativity  difference between constituent atoms. If electronegativity difference between constituent atoms is significantly higher, ionic bond formation is preferred. On other hand, low difference in electronegativity values, favours formation of covalent bond.

What would diluting the vinegar do to the rate of a reaction between vinegar and sodium hydroxide? decrease the rate of reaction
GarryVolchara [31]
Vinegar is aceti acid diluted in water.

The reaction of vinegar with sodium hydroxide is:

CH3COOH + NaOH ---> CH3COONa + H2O

That is an acid-base reaction.

The speed of reaction is proportional to the concentrations of the reactants.

Then, given thatn when you dilute the vinegar you decrease the concentration of CH3COOH, the rate of reaction will decrease.

Answer: decrease the rate of reaction.

What percentage of the mass of hydrofluoric acid (HF) is contributed by hydrogen?
Morgarella [4.7K]

This problem is asking for the percent by mass of hydrogen in hydrofluoric acid. At the end, the answer turns out to be D. 5%​ as shown below:

<h3>Percent compositions:</h3>

In chemistry, percent compositions are used for us to know the relative amount of a specific element in a compound. In order to do so for hydrogen, we use the following formula, which can also be applied to any other element in a given compound:

\% H=\frac{m_H*1}{M_{HF}}*100\%

Where m_H stands for the atomic mass of hydrogen and M_{HF} for the molar mass of hydrofluoric acid. In such a way, we plug in the atomic masses of hydrogen (1.01 g/mol) and fluorine (19.0 g/mol) to obtain:

\% H=\frac{1.01g/mol*1}{1.01g/mol+19.0g/mol}*100\%\\\\\% H=5\%
