Average speed = distance traveled divided by time taken. so 10 divided by 5, which is 2. her average speed was 2m per second. hope this helps!

said law, the volume of a gas varies inversely with pressure. Boyle's law is
one of the gas laws we have. According to this law, at a fixed amount of an
ideal gas which is at constant temperature, the pressure and volume are
inversely proportional with each other. <span>The variables are volume and
pressure.</span></span>
The answer is B. Heat flows from the hand to the ice cream. The state of equilibrium won't occur for this since the only reactant is heat.
Ionic compounds are the combination of two elements, one of which is a metal, while the other is a nonmetal. The intermolecular forces binding them is called an ionic bond. To name an ionic compound, take the name of the metal element first, followed by the nonmetal, but adding the suffix -ide. For example, NaCl is named as sodium chloride.
Na = 23 x 2.40 = 55.2
O = 16 x 2.40 = 38.4
H = 1 x 2.40 = 2.40
55.2 + 38.4 + 2.4 = 96
2.40 mol of NaOH = 96 amu
