Oxygen and neon are both elements. Oxygen has 8 electrons and 8 protons. Neon has 10 electrons and 10 protons. Oxygen is also a non-metal element and Neon is a noble gas.
Solution
Given mass of FeBr2 = 85.5 g
Molar mass of FeBr2 = 215.65
No. of Moles of FeBr2 = Given Mass / Molar mass = 85.5 / 215.65
No. of Moles = 0.3964
Given Volume is 450 mL i.e. 0.450 L
Now Concentration = 0.3964/0.450
Hence Concentration = 0.881 mol/L
Answer:
very confused but, hope this helps in a way-:
What can be the Results and conclusion to this experiment?
1) Observation: Plants grow well in the ant habitats.
2) Question: Does ants help in plant's growth?
3) Hypothesis: There is a mutualistic relationship between plants and ants.
4) Experiment: This hypothesis can be experimented using ecological study design. The growth of two plants, one growing in the presence of ants and the other in the absence of ants are compared. All other variables like temperature, moisture, soil and nutrients are maintained constant. The growth in plants are measured after two months. It will be observed that the growth of plants in the presence of ants is more than the other plant. Ants help in aerating the soil and protects the plant from herbivores, and fungal attack.
Answer:
the answe would be (c) temperate continental
Explanation:
Answer:
Because it will allow a bigger temperature change.
Explanation:
The specific heat of the metal can be calculated by the heat change between it and the water. The total amount of heat must be 0, thus, the heat of the metal (Qm) plus the heat of water (Qw):
Qm + Qw = 0
The heat is the mass multiplied by the specific heat (c) and by the temperature change:
mm*cm*ΔTm + mw*cw*ΔTw = 0
mm*cm*ΔTm = - mw*cw*ΔTw
So, as higher is the value of mw, as low is the value of ΔTw, and if ΔTw is very low, and so the calculations may not be precise.
