In a single replacement reaction which element must be most active

the single element (for A+)

Who illustrated Savvy by Ingrid Law

Elizabeth Parker illustrated Savvy but Hennie Haworth created the cover picture.

Identify the diatomic element in this group

Iodine or Fluorine . . . A+

Choose the element that is most active

Mg

Predict and choose the most correct products formed from the reaction between iron III oxide and potassium metal

Omar was recording his preliminary data before beginning an experiment on gas behavior The room temperature was 298K and atmospheric pressure was 1 ATM Omar used an acceptable abbreviation of thes

STP

What is the best definition of manometer

an instrument that is used to measure gas in a closed container. A+

Will measured a gas at 30.0degrees Celsius and 752.0 mmHg What would his measurements be if expressed in Kelvin and atmospheres

303k and 0.989 atm.... A+

Pressure is used to increase the volume of gas

Pressure is used to increase the volume of gas in Boyle's law.

Angelo noticed his lab partner had incorrectly recorded the pressure of a gas in mmHg rather than in atmospheres as their teacher requested When he corrected the mistake Angelo recorded 751.5 mmHg

the answer is 0.99 :)

Choose the law that matches this definition As the temperature on a gas increases the volume of the gas must also increase to maintain constant pressure

On the list of choices that you posted along with the question,

that law doesn't appear.

Predict the product of this compound ZnO plus COea æ

ZnCo(little 2)

Can you get a shiny Ho-oh in Pokemon Colosseum

No the Ho-oh is set to be a regular colored Ho-oh and is always set to be the same level and from the same OT (Mattle).

Which of these elements is not diatomic potassium chlorine iodine or hydrogen

Potassium Chloride is not diatomic. Although chloride is a diatomic molecule (BrINClHOF), the formula for Potassium Chloride is KCl not KCl2. Therefore, it is not diatomic.

What law matches this formulaPV c

Boyle's Law, but it does go further than PV = c.

How do you convert the temperature 84.7 degree C to kelvin

To convert deg C to Kelvin, simply add 273.15

Choose the best definition of STP

a term that indicates a combined measurement of standard atmospheric pressure and room temperature. A+
