Answer:
10 400 N
Explanation:
A drag force is an oppositional or limiting force which must be overcome before an object must move wit a force. The lesser the drag force, the higher the probability that an object would move easily.
From the question give, the resultant force of the was is 600 N and force from the engine - 11 000 N.
Drag force = 11 000 - 600
= 10 400 N
The drag force on the car is 10 400 N.
This shows that the car would not move since the drag force (10 400 N) is far greater than the resultant force(600 N).
I think u turn down the heat not to sure
Answer:
0.500 moles of CO2 has a volume of 11.2 L at STP (option B)
Explanation:
Step 1: Data given
Volume of a gas at STP = 11.2 L
STP: Pressure = 1 atm and temperature = 273 K
Step 2: Calculate volume
p*V= n*R*T
V = (n*R*T)/p
⇒with V = the volume of the gas = TO BE DETERMINED
⇒with n = the number of moles of the gas
⇒with R = the gas constant = 0.08206 L*atm/mol*K
⇒with T = the temperature = 273 K
⇒with p = the pressure of the gas = 1 atm
A
) 0.250 mole of NH3
V = (0.250 * 0.08206 * 273) / 1
V = 5.6 L
B
) 0.500 mole of CO2
V = (0.500 * 0.08206 * 273) / 1
V = 11.2 L
C
) 0.750 mole of NH3
V = (0.750 * 0.08206 * 273) / 1
V = 16.8 L
D) 1.00 mole of CO2
V = (1.00 * 0.08206* 273) / 1
V = 22.4 L
0.500 moles of CO2 has a volume of 11.2 L at STP (option B)
Answer:
True becouse any graphs can show info
Answer:
Carbon has six electrons (2 core and 4 valence), and can form four bonds with neighboring atoms. Nitrogen has seven electrons (2 core and 5 valence)(1s2, 2s2, 2px1, 2py1, 2pz1). So if you are following the rules, you might well assume that nitrogen would be able to form five bonds (after all, it has five valence electrons.)
