What are the four main properties of transition elements? Properties of transition elements include: have large charge/radius ratio; are hard and have high densities; have high melting and boiling points; form compounds which are often paramagnetic; show variable oxidation states; form coloured ions and compounds; form compounds with profound catalytic activity; What are the uses […]

Is 200ml same as 200g? How many grams is 200ml? – 1 ml equals 1 gram, therefore there are 200 grams in 200 ml. To convert 200 ml to g, simply multiply 200 ml by 1 to get grams. How many grams is 200ml of milk? Conversion Table mL Grams 50 mL 50 grams 100 […]

What charge is a ionic bond? The atoms in chemical compounds are held together by attractive electrostatic interactions known as chemical bonds. Ionic compounds contain positively and negatively charged ions in a ratio that results in an overall charge of zero. The ions are held together in a regular spatial arrangement by electrostatic forces. Is […]

What is the value of N and L for 3d? We see clearly for 3d orbital value is n = 3, l = 2 and m = -2,-1,0,1,2. What are the possible values of n and ML for an electron in a 4p orbital? What Are The Possible Values Of N And M L For […]

What is the atomic mass of silver round to nearest tenth? Silver has the Atomic Mass weight of 107.87. Round to the nearest whole number. The mass number of silver is therefore 108. Example 3 – mass number of Neon: The element Neon (Symbol Ne) has the Atomic Number of 10. What is the mass […]

What two simple machines make a wheelbarrow? Look at the wheelbarrow in the Figure below. It is used to carry heavy objects. It consists of two simple machines: a lever and a wheel and axle. Effort is applied to the lever by picking up the handles of the wheelbarrow. What is the difference between fixed […]

Which statement best describes the difference in air temperature and humidity between the cP and mT? What is the difference in the air temperature and humidity between the cP and mT air masses? The cP air mass is warmer and less humid. The cP air mass is colder and more humid. The mT air mass […]

Who started the Vietnam War protests? Vietnam War Protests: The Beginnings of a Movement In August 1964, North Vietnamese torpedo boats attacked two U.S. destroyers in the Gulf of Tonkin, and President Lyndon B. Johnson ordered the retaliatory bombing of military targets in North Vietnam. Why were people concerned that the draft was unfair? Until […]

What is formed when two or more substance are combined? When two or more elements combine to form a new substance, it is called a compound. There are many different types of compounds, because atoms of elements combine in many different ways to form different compounds. Examples include water (H2O) and table salt (NaCl). The […]

How do you motivate yourself to participate in any activities? Advertisement Make it fun. Find sports or activities that you enjoy, then vary the routine to keep it interesting. Make physical activity part of your daily routine. If it’s hard to find time for exercise, don’t fall back on excuses. Put it on paper. Join […]
