Answer:
hot, less, rise, top, cold, closer, more, sink
Explanation:
I'm in high-school done this long time ago
To change only one variable which is very important than to test the experiment to match the hypothesis again, I think. It’s been a while since I was on that lesson♀️
Answer:
83.69 gm
Explanation:
molar weight of N2 = 28
Find the number of moles then multiply by this
1.8 x10^24/ (6.022x10^23) * 28 =83.69 gm
The flame test is commonly used to identify different metal ions by how they get excited in the presence of a flame.
Typically a nichrome wire is dipped in a solution of metal cations and then presented to a flame. The flame emits a different color than normal, depending on the type of metal cation. Each metal ion gets excited by the flame and as the electrons change energy levels they emit a photon of light, thus changing the color. Since each metal cation has unique energy levels, the colors differ depend on the metal cation.
I hope this helps.
Answer:
SUBSTANCES
Explanation:
According to this question, Jasmine is conducting an experiment in order to see how much temperature change occurs when three different substances are heated. Based on this experiment, the INDEPENDENT VARIABLE, which is the variable that is changed or manipulated is SUBSTANCES.
A controlled experiment is an experiment where all other variables except the INDEPENDENT VARIABLE is kept the same or unchanged. The independent variable is the only variable allowed to change, which in this case is the SUBSTANCES USED.
