La leche se considera un alimento basico por su elevado contenido de nutrientes su densidad es de 1,4g/ml. Si se hace una compra de 7 bolsas de leche cada una con un volumen de 900m cual es la masa total de la leche expresada en kilogramos?
Answer:
8.82 kg es la masa total de leche
Explanation:
Consideraremos que el volumen de cada bolsa de leche es de 900 mL.
Sabiendo que tenemos en total 7 bolsas, el volumen final en litros que tenemos disponible es de:
900 mL . 7 = 6300 mL
Utilizando la densidad podemos calcular la masa de leche que tenemos en el total de las 7 bolsas
Densidad = masa / volumen
Densidad . volumen = masa → 1.4 g/mL . 6300 mL = 8820 g
Convertimos la masa de gramos a kg
8820 g . 1 kg /1000g = 8.82 kg

What type of decay does Am-241 undergo to become Np-237?
a. Alpha decay
c. Positron emission
b. Beta decay
d. Electron capture
The type of decay that Am-241 undergoes to become Np-237 is alpha decay. The correct option is a.
What is alpha decay?Alpha decay is a type of decay or transformation in which a nucleus emits an alpha particle and change into different atomic nuclei. The atomic number reduces by 2 and the mass is reduced by 4.
Am-241 is an isotope of the chemical element americium. It is a radioactive element and its radioactive decay period is 432.2 years. It is used in the testing of machinery.
When the nucleus of Am changes or emits a radioactive particle. It converts into Np-237. The process is called alpha decay. The atomic mass is reduced by four, and the 241 converts into 237, which become neptunium.
Thus, the correct option is a. Alpha decay.

Explain what you discovered from the Simulation about why food coloring spreads faster in warmer water.
Answer:
The food colouring mixes through the hot water faster than it mixes with the cold water, this is because in hot water the water molecule have more energy and are moving faster than the molecules of cold water .This makes it easier for the food colouring to get mixed quickly through the hot water.

Facts about flooding
Answer:
No region is safe from flooding. All 50 states are subject to flash floods.[1]
Flash floods can bring walls of water from 10 to 20 feet high.[2]
A car can be taken away in as little as 2 feet of water.[3]
To stay safe during a flood, go to the highest ground of floor possible. If your skin comes in contact with flood water, make sure to wash it with soap and disinfected water because the contents are unknown.[4]
Flooding is caused by spring thawing (snow and frozen grounds melting in the spring), heavy rains, snow melt runoffs, flash floods, and mudflows.[5]
Floods are the most widespread natural disaster aside from wildfires. 90% of all U.S. natural disasters declared by the President involve some sort of flooding.[6]
In preparation for a flood, it is important to stock up on first aid items, non-perishable foods, 3 gallons of water per person for 3 days, battery operated radio for weather reports, extra batteries, personal hygiene necessities.[7]
Based on Floodsmart, a 2,000 square foot home undergoing 12” of water damage could cost more than $50,000.[8]
Since flood damage is almost never covered by homeowners insurance, flood insurance is important for people living in high-risk flood zones.[9]
To stay safe during a flood, go to the highest ground of floor possible. If your skin comes in contact with flood water, make sure to wash it with soap and disinfected water because the contents are unknown.[10]
Communities particularly at risk are those located in low-lying areas, near water, or downstream from a dam.[11]

What is the molecular formula for a compound that is 34.31% sodium, 17.93% carbon, 47.76% oxygen and has a molar mass of 134.00g?
Answer: Na2C2O4 probably sodium oxalate
Explanation: assume you have 100 g substance.
Mass of Na is m(Na) = 34.31 g, m(C) = 17.93 g and m(O) = 47.76 g.
Calculate moles n(Na) = 34.31 g/22.99 g/mol= 1.49 mol.
For C n(C) = 1.49 mol and n(O) = 2.985. You divide all by 1.49 you
Get n(Na) : n(C) : n(O) = 1:1:2 M(NaCO2) = 67 g/mol.
Divide 134:67 = 2. You get formula Na2C2O4

A mixture of Oxygen and Hydrogen occupies a pressure of 101.3kPa. The pressure of Hydrogen is 56kpa. Calculate the pressure of oxygen.
Answer:
45.3 KPa
Explanation:
From the question given above, the following data were obtained:
Total pressure (Pₜ) = 101.3 KPa
Pressure of Hydrogen (Pₕ) = 56 KPa
Pressure of Oxygen (Pₒ) =?
The pressure of oxygen in the mixture can be obtained as follow:
Pₜ = Pₕ + Pₒ
101.3 = 56 + Pₒ
Collect like terms
101.3 – 56 = Pₒ
Pₒ = 45.3 KPa
Thus, the pressure of oxygen in the mixture is 45.3 KPa

if water is added to a 0.70 molar solution of CuSO4 what will change
A. molarity will increase
B. Molarity will decrease
C. the amount of CuSO4 will decrease
D. No change in molarity or amount of salute
Answer:
B. Molarity will decrease
Explanation:
Molarity is one of the measures of the molar concentration of a solution. It is calculated by dividing the number of moles of the solute by the volume of the solvent. This means that the higher the amount of solute in relation to the volume of solvent, the higher the molarity of that solution.
In essence, adding water to a solution dilutes it i.e it increases the solvent's volume in relation to the solute, causing the molarity to decrease. In a nutshell, diluting a solution (by adding water or more solvent) causes the molarity of such solution to decrease. For example, if water is added to a 0.70 molar solution of CuSO4, the molarity of the solution will DECREASE.
