The correct answer is option B, above a bowl of ice water.
Standard temperature is zero degrees Celsius (°C) or 32 degrees Fahrenheit (°F). Standard pressure is 760 mmHg or 1 atm.
Both the conditions of Standard temperature and standard pressure is basically the freezing point of pure water at sea level.
Thus the air above a bowl of ice water is at standard temperature and pressure
Answer is B for Edmentum users
Answer:
The ionic bond occurs between two different atoms (metal and nonmetal), while the covalent bond occurs between two equal atoms (nonmetals),
Another difference between these is that the covalent bond is an electron compartment, while in the ionic bond there is an electron transfer.
Metal bonding occurs when metals are combined with each other. Metal atoms need to give up electrons to reach the configuration of a noble gas. In this case, the metals lose the valence electrons and an electron cloud forms between the positive nuclei.
The answer to this question is:
The mobility of electrons.

The molar mass of Sr is 87.62u
9.75 x 10^5
A number in scientific notation has the form a x 10^b where
• a is the coefficient
• b is the exponent
Here are the steps to convert a number greater than 1 to scientific notation.
a) Find the coefficient
Put the decimal point after the first digit and drop the trailing zeroes
9.75 000
The coefficient is 9.75.
b) Find the exponent
Count the number of digits after the first digit.
In 975 000 there are five digits after the 9. Therefore, the exponent is 5.
c) Write the number
We write 975 000 as 9.75 x 10^5.
