Answer:

How the incident happened

Any chemicals involved in an incident

Any other hazards present in the lab

Explanation:

Above are the types of information that are necessary to communicate with emergency responders. The emergency responders ask the first question that how the incident happened. After that they ask that is there any harmful chemicals are present in the laboratory or what types of chemicals present in the laboratory. These questions were asked by the emergency responders in order to give the patient a suitable treatment.

¿Cuál de los siguientes no es un ejemplo de movimiento de masas?
babunello [35]

Which of the following is not an example of a mass movement?

to. a. Ground slides  b) acid rain  c. mud flow  d. drop

Answer:

b) acid rain

Explanation:

Acid rain is not an example or a type of mass movement.

Mass movement or mass wasting is the movement of rocks, soils and other debris downslope under the influence of gravity.

Water, slope and gravity are triggers of mass movement.

  • Acid rain is a not a form of mass movement
  • It occurs with some certain gases mixes rain water to produce an acidic precipitation.
  • When the water falls to the each surface, it causes problems to the ecosystem and can also corrode building materials.

2074 Set B Q.No. 1 What mass of nitrogen will be requires
timurjin [86]

140 g of nitrogen (N₂)

Explanation:

We have the following chemical equation:

N₂ + 3 H₂ -- > 2 NH₃

Now, to find the number of moles of ammonia we use the Avogadro's number:

if        1 mole of ammonia contains 6.022 × 10²³ molecules

then   X moles of ammonia contains 6.022 × 10²⁴ molecules

X = (1 × 6.022 × 10²⁴) / 6.022 × 10²³

X = 10 moles of ammonia

Taking in account the chemical reaction we devise the following reasoning:

If        1 mole of nitrogen produces 2 moles of ammonia

then  Y moles of nitrogen produces 10 moles of ammonia

Y = (1 × 10) / 2

Y = 5 moles of nitrogen

number of moles = mass / molecular weight

mass = number of moles × molecular weight

mass of nitrogen (N₂) = 5 × 28 = 140 g

What is the predicted order of first ionization energies from highest to lowest for lithium (Li), sodium (Na), potassium (K), an
frutty [35]
The first ionization energy is the energy that the atom lost its first electrons. The energy decrease and the atom is more reactive. So from highest to lowest is Li>Na>K>Rb.

Density is an intensive physical property that relates the mass of an object to its volume. Density, which is simply the mass of
xz_007 [3.2K]

Answer: 40731.8 grams of this gasoline would fill a 14.6gal tank

Explanation:

Density is defined as the mass contained per unit volume.

Density=\frac{mass}{Volume}

Given : Mass of gasoline = ?

Density of the gasoline = 0.737g/ml

Volume of the gasoline = 14.6gal = 55267.01 ml           (1gal=3785.41ml)

Putting in the values we get:

0.737g/ml=\frac{mass}{55267.01ml}

{\text {mass of gasoline}}=40731.8g

Thus 40731.8 grams of this gasoline would fill a 14.6gal tank
