Answer:
0.642 g
Explanation:
La ecuación balanceada es:
- 2Mg + 2CuSO₄ + H₂O → 2MgSO₄ + Cu₂O + H₂
Primero <u>convertimos 1.89 g de Cu₂O en moles</u>, usando su <em>masa molar</em>:
- 1.89 g ÷ 143.09 g/mol = 0.0132 mol Cu₂O
Después <u>convertimos moles de Cu₂O en moles de Mg</u>, usando los <em>coeficientes estequiométricos</em>:
- 0.0132 mol Cu₂O * = 0.0264 mol Mg
Finalmente <u>convertimos moles de Mg en gramos</u>, usando la <em>masa molar de Mg</em>:
- 0.0264 mol Mg * 24.305 g/mol = 0.642 g
Animals provide many benefits to people. Many people interact with animals in their daily lives, both at home and away from home. Animals provide food, fiber, livelihoods, travel, sport, companionship, and education for people across the globe. Millions of households in the United States have one or more pets. We might come into contact with animals in either urban or rural settings, during travel, while visiting animal exhibits, or while enjoying outdoor activities.
However, animals can sometimes carry harmful germs that can spread to people and cause illness – these are known as zoonotic diseases or zoonoses. Zoonotic diseases are caused by harmful germs like viruses, bacterial, parasites, and fungi. These germs can cause many different types of illnesses in people and animals, ranging from mild to serious illness and even death. Animals can sometimes appear healthy even when they are carrying germs that can make people sick, depending on the zoonotic disease.
Answer:
2c +o2=2co
Explanation:
Check and u will see that all the elements in the left side of the chemical reaction are equal to those on the right
Answer: True
Explanation:
Air is indeed a mixture as the component compounds and mixtures retain their individual properties as opposed to a compound that sees the component elements lose some of theirs.
Air is a type of mixture known as a homogeneous mixture which means that no matter what quantity of air is present, the composite elements (Oxygen, nitrogen etc) and compounds( carbon dioxide etc) are of the same quantity.
I think it’s A but I might be wrong
