give me a fully balanced equation of lead monoxide and nitric acid
Answer:
Explanation:
Lead Monoxide: PbO
Nitric Acid: HNO3
PbO + 2 HNO3 ---> Pb(NO3)2 + H2O
Answer:
Explanation:
mono mean single so lead monoxide is PbO
nitric acid is HNO3
both Pb n O are double-charged while H n NO3 are single
so balanced eqn is:
PbO + 2HNO3 -> Pb(NO3)2 + H2O
True or false

El suero fisiológico tiene una concentración de 8,78 gr/lt. Calcula la masa de NaCl que ingresa en el organismo de un paciente al que se le administra suero durante 4 hs con una velocidad de goteo de una gota por segundo (Volumen gota: 0,05 ml)
Un paciente que recibe suero fisiológico a una velocidad de infusión de 1 gota = 0,05 ml por segundo recibirá en 5 horas 790 grs de NaCl, tomando en cuenta que la solución acuosa de suero fisiológico contiene 0,878 grs/mL de NaCl.
Explicación
Los datos que se tienen son:
Concentración de NaCl 0,878 grs/mlVolumen de la gota: 0,05 ml/gotaVelocidad de infusión 1 gota/ seg = 60 gotas/ min = 3 ml/minTiempo de infusión = 5 horas = 300 minutosYa establecidas las respectivas conversiones se trata de determinar qué volumen de suero fisiológivo se ha infundido al paciente en 5 horas
Si se infunden 3 ml cada minuto, ¿Cuánto se habrá infundido en 300 minutos?
3 ml ______________ 1 min
X ________________ 300 min
X = (300 min x 3 ml) / 1 min
X = 900 ml
Como en 5 horas el paciente ha recibido 900 ml de suero, se determina la cantidad de NaCl que se encuentra en ese volumen de líquido
0,878 grs __________ 1 ml
X ________________ 900 ml
X = (900 ml x 0,878 grs) / 1 ml
X = 790 grs de NaCl
If 14.7 cm3 of alcohol is present in 70 cm 3 of its aqueous solution, the percentage by volume of alcohol will be?
Answer: The percentage by volume of alcohol will be 21%.
Explanation:
Given: Volume of solute = 14.7 [tex]cm^{3}[/tex]
Volume of solvent = 70 [tex]cm^{3}[/tex]
Formula used to calculate percentage by volume is as follows.
[tex]Percentage volume = \frac{volume of solute}{volume of solvent} \times 100[/tex]
Substitute the values into above formula as follows.
[tex]Percentage volume = \frac{volume of solute}{volume of solvent} \times 100\\= \frac{14.7 cm^{3}}{70 cm^{3}} \times 100\\= 21 percent[/tex]
Thus, we can conclude that the percentage by volume of alcohol will be 21%.
A balloon at sea level on earth (1 atm pressure, 19°C) takes up 14.5 L of space. The balloon travels to Mars where atmospheric pressure is 4.55 torr and the temperature is -55°C What is the volume of the balloon on Mars?
Answer:
1807.24L
Explanation:
Using combined gas law equation:
P1V1/T1 = P2V2/T2
Where;
P1 = pressure on Earth
P2 = Pressure on Mars
V1 = volume on Earth
V2 = volume on Mars
T1 = temperature on Earth
T2 = temperature on Mars
According to the information provided of the balloon in this question;
P1 = 1 atm
P2 = 4.55 torr = 4.55/760 = 0.00599atm
V1 = 14.5L
V2 = ?
T1 = 19°C = 19 + 273 = 292K
T2 = -55°C = -55 + 273 = 218K
Using P1V1/T1 = P2V2/T2
1 × 14.5/292 = 0.00599 × V2/218
14.5/292 = 0.00599V2/218
Cross multiply
14.5 × 218 = 292 × 0.00599V2
3161 = 1.74908V2
V2 = 3161 ÷ 1.74908
V2 = 1807.24L
It is known that oxygen contains 1 percent of the air. If 50 liters of wind, how much oxygen is needed?
Answer:
Amount of oxygen needed is 5,000 liter
Explanation:
Given:
Percent of air in oxygen = 1%
Find:
Oxygen if 50 liter of wind
Computation:
Oxygen if 50 liter of wind = 50 liter wind[100% / 1% ]
Oxygen if 50 liter of wind = 50 liter wind[100]
Oxygen if 50 liter of wind = 50[100]
Oxygen if 50 liter of wind = 5,000
So,
Amount of oxygen needed is 5,000 liter

The question is incomplete, the complete question is;
As Danny was pouring cereal for his breakfast, he noticed that the cereal box says that the cereal contains 5 milligrams of iron per serving. Danny decided to perform an experiment to test this claim. He found that the cereal contains 4.6 milligrams of iron per serving. Based on Danny's measurement, the value reported on the label is ( CORRECT OR INCCORECT) because A: (IT IS DIFFERENT FROM THE VALUE DANNY MEASURED) B: (IT IS REORTED TO THE NEAREST MILLIGRAM) C: (IT USES THE SAME UNITS THAT DANNY USED).
Answer:
CORRECT because IT IS REORTED TO THE NEAREST MILLIGRAM
Explanation:
In mathematics, values may be rounded up or down as required. In the case of this measurement of cereals by Danny, it is customary to measure the amount of iron per serving to the nearest milligram.
As such, even though Danny found out that the actual amount of iron per serving in the cereal is 4.6 milligrams, the value reported on the cereal box is still correct because it was reported to the nearest milligram hence the value had to be rounded up.
Using the balanced equation below, how many grams of cesium fluoride would be required to make 73.1 g of cesium xenon heptafluoride?
CSF + XeF6 → CsXeF7
Answer:
27.9 g
Explanation:
CsF + XeF₆ → CsXeF₇
First we convert 73.1 g of cesium xenon heptafluoride (CsXeF₇) into moles, using its molar mass:
Molar mass of CsXeF₇ = 397.193 g/mol73.1 g CsXeF₇ ÷ 397.193 g/mol = 0.184 mol CsXeF₇As 1 mol of cesium fluoride (CsF) produces 1 mol of CsXeF₇, in order to produce 0.184 moles of CsXeF₇ we would need 0.184 moles of CsF.
Now we convert 0.184 moles of CsF to moles, using the molar mass of CsF:
Molar mass of CsF = 151.9 g/mol0.184 mol * 151.9 g/mol = 27.9 gWhat would you need to do to calculate the molality of 10 mol of NaCl in 200

9. Explain why you can't write the formula of the ionic compound that forms between Fe
and S?
Answer:
See explanation
Explanation:
According to Fajan's rules, the degree of covalent character of a bond depends on the relative polarizing power of ions.
Generally, ions become more polarizing when they are small and highly charged. Large negative ions are more polarizable than small ones.
A very small positive charge concentrated on a small area such as in Fe^2+ makes the ion highly polarizing. Also, a large negative ion such as S^2- is highly polarizable.
As a result of these FeS has considerable covalent character hence we can not simply write the formula of the ionic compound that forms between Fe and S?

If a gas is pumped from a smaller container to a container that is twice the size, and its pressure is kept the same, then what happens to the temperature of the gas?
Answer: If a gas is pumped from a smaller container to a container that is twice the size, and its pressure is kept the same, then temperature of the gas increases twice.
Explanation:
Charles law states that at constant pressure, the volume of a gas is directly proportional to the temperature.
That is, [tex]V \propto T[/tex].
So, when a gas is pumped from a smaller container to a container that is twice the size shows that volume is increasing by 2 times and its pressure is kept the same.
Therefore,
[tex]2V \propto 2T[/tex]
This means that the temperature of the gas will also become twice its initial temperature.
Thus, we can conclude that if a gas is pumped from a smaller container to a container that is twice the size, and its pressure is kept the same, then temperature of the gas increases twice.

The structure and bonding of diamond, which is formed from graphite at extreme pressures, should be similar to that of elemental:
Answer:
silicon and germanium.
Explanation :
The passage states that at extreme pressures an elemental solid assumes the structure and bonding characteristics of a heavier element in the same column of the periodic table. The structure and bonding of diamond, which is a form of carbon, would therefore be most like other elements in the same group of the periodic table as carbon. This group contains silicon and germanium.
