Is negative free cash flow a bad sign? Although companies and investors usually want to see positive cash flow from all of a company’s operations, having negative cash flow from investing activities is not always bad. Can you have negative cash flow and positive profit? Cash flow is the net amount of cash and cash-equivalents […]
Why does losing gaining an electron cause the other element to gain lose atoms?
Why does losing gaining an electron cause the other element to gain lose atoms? Answer: A positive ion is formed where an atom has more protons than electrons. Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to […]
What are the major types of work?
What are the major types of work? First, let’s take a look at the five kinds of work we do every day: Reactionary Work. Planning Work. Procedural Work. Insecurity Work. Problem-Solving Work. How many types of work do we have? Four Types What is considered an IT project? An information technology project is a temporary […]
Is sodium and magnesium an ionic compound?
Is sodium and magnesium an ionic compound? There is a strong electrostatic force of attraction between these oppositely charged ions – this is called an ionic bond. The slideshow shows ionic bonds being formed in sodium chloride, magnesium oxide and calcium chloride. How do you combine ionic charges? To find the formula of an ionic […]
What is the actual weight of molecule of water?
What is the actual weight of molecule of water? Therefore, 18g of mass of water is occupied by 6.022×1023 number of molecules. Therefore, we can calculate the mass of one molecule of water by dividing the mass of one mole of water and Avogadro number. The actual weight of a molecule of water is calculated […]
How gravity affects the movement of object?
How gravity affects the movement of object? On Earth, gravity pulls all objects to Earth’s center. Gravity acts on all masses equally, even though the effects on both masses may be different because gravity causes all objects to fall at the same constant rate of 9.8 m/s2. An object in free fall means that the […]
Why does O 3 not exist?
Why does O 3 not exist? An electrically-neutral oxygen atom gains two electrons to form an oxygen ion with two negative charges. The ion would thus be highly unstable and potentially readily lose that outermost electron and return to O3− as the ten inner shell electrons seek to get rid of the additional electron. Why […]
What is the inhalation process?
What is the inhalation process? When you inhale (breathe in), air enters your lungs and oxygen from the air moves from your lungs to your blood. At the same time, carbon dioxide, a waste gas, moves from your blood to the lungs and is exhaled (breathe out). This process is called gas exchange and is […]
Which liquid would evaporate most quickly at room temperature?
Which liquid would evaporate most quickly at room temperature? Acetone has the weakest intermolecular forces, so it evaporated most quickly. Water had the strongest intermolecular forces and evaporated most slowly. Which type of liquid dries the fastest? The rubbing alcohol evaporated the fastest followed by water and finally vinegar. Olive oil didn#t seem to evaporate […]
What is the function of voluntary muscles?
What is the function of voluntary muscles? Voluntary muscles are the muscles that are under conscious control and can be controlled at will or we can choose when to use them. They are also known as skeletal muscles as they are attached to the bones. Voluntary muscles are responsible for the movement of body parts […]
